They did send me another set of control arms which was nice of them but they are also a bit short. I did make some modifications to make them work. the kit is supposed to use 8 washers per side but i needed more to align the toe adjuster up, I do have T3 spindles so that may be part of the variation I was seeing. So I machined some spacers because stacking 15 washers was not my favorite design. The spacers tightly fits over the spindle and then takes up about an inch of space and allows 5 washers for "adjustment" The guy from apex did called me and we chatted for a bit about some other design concerns I have. Which was great and he took it well. Apparently they just aren't good at measuring things. They said they are going to try and make me a shorter set of front control arms aswell because the front setup at its absolute max shortest setting is still .375" wider than the stock assembly which doesn't allow me to use any of the roll center or control arm adjustments with my wheel and tire combo. I was hoping to correct geometry with everything being adjustable but that's not the case since the crossmember mounting points are wider than the factory one so I had to max everything out to its shortest point to even fit. With that said I have been plugging away at stuff, brake lines are ran, rear suspension is in, engine is assembled. adapter kit for the trans is machined, body panels are getting put on. started on the interior, everything takes so long. painting brackets and hardware and aligning everything but i am very happy with how its coming out. I was told the car came with a 240sx diff, its actually a j30 diff so it has a 3.91 gear ratio. That may be a slight advantage so not to mad. Anyway, after all this reading. enjoy some photos.

My pretty long weekend has come to an end and I’m pleased to say that I accomplished a lot in those four days. I started off with finishing the installation of the interieur. Because of the Apex Engineered rear strut brace I had to make some modification to the floor board, carpet and strut covers. This took a bid more time then I had hoped but I managed to finish the interieur within a day. Me and my girlfriend are still slowly working on the seats and the door card but we will probably end up installing those last. Next came (for me) one of the more exiting parts, starting work on the rear end! So it was time to put down my QuickJack’s and take the wheels off….. Never mind, the previous owner installed locking wheel nuts on all four corners and all four lugs at that! So a trip to the parts store for a lug nut removal socket and some angle grinder lathe action later (and about 3 hours) the wheels where finally off. If you told me the rear end was still factory fresh then I would have believed you. All the bolts where incredibly stuck and most of them where cross threaded (thanks previous mechanic). Not to mention all the rubber bushings where pretty worn out. Luckly with some heat, penetrating oil and a hammer all of the bolts came out. The threads there even still usable, lucky me! Before the reinstallation I did retape all the threads and cleaned up all the nuts and bolts. Before reinstalling everything I took my time to replace the differential gasket and change the differential oil for some new Motul 75W90. I also replaced the mustache bar bushings for polyurethane bushings. Removing the old bushings went pretty smoothly with a saw, some fire and a bit of patience. The only problem I had was during reinstallation of the mustache bar. The only way it would fit back in was by rotating the bar 180 degrees, may explain the difficulty removing the bar in the first place. I don’t know if this is the correct orientation but it wouldn’t fit any other way and I can find many pictures online of the bar in both orientations. I decided to leave the bar as is and finish up by finally installing the Apex rear control arms. Man it feels good to finally make some upgrades, the car feels more and more my own. The refresh of the rear end took a bit more time then I initially thought (two days) so before starting on the front, knowing I couldn’t finish it this weekend, I decided to take on some smaller jobs first. The bodywork on the car is a bit of a slopy mess with some signs of surface rust all along the lower edges of the rear of the car together with fading powder coating / paint on the fuel tank. It may be a bit unorthodox but seeing as I have a rust converter spray / paint that’s pretty close in color to the car I just took a sander to the edges and sand away the rust and knock down the body filler on the bottum edge. I also sanded smooth the fuel tank and used the last bit of remaining texture spray to hide the imperfections on the fuel tank. And even if I say so myself I’m pretty pleased with the result, at least the rear of the car is now less of an eyesore. During all the work on the underside of the car I noticed a small oil leak coming from the speedometer pinion gear. A quick search online showed it had an o ring sealing the pinon gear so I quickly popped it partially out and replaced the o ring inside. Another small job of the list! As I still had a bit of time left in the day I tried my luck at removing at least the front control arms. And I don’t know what magic was used but this was the easiest disassembly ever! A little spray of penetrating oil and a quick tuck on the wrench and out came the bolts by hand. Even the front ball joint and tie rods came right out! All in all it was a very productive weekend. I just placed an order for some small stuff like a few new rubbers, normal lug nuts and two new horns (mine have underseal in them) and will be continuing my refresh of the front suspension next weekend. That will be a bit more tricky as I need to replace the oil pan gasket and the front crossmember. Also I know you guys probably find my work space pretty interesting so enjoy!

thanks for the photos and description. It may just be the factory had more variation than we'd expect from modern cars but the 70s where a rough time for the automotive quality so its possible. I do also understand that I am mixing two different brands on to a 50+ year old car. With the T3 drop downs being billet they do not have any forward or backwards motion so the width of the arms need to be pretty spot on.

I finally got around to refurbishing the rear end and installing the Apex rear control arms. I checked my control arms and they too measured in at 15,5” inches. But the funny thing is is that they where the same length as the original control arms!! Anyway the install went smoothly except for the fact that I had to rotate the mustache bar 180 degrees as I couldn’t for the life of me install it another way with the new bushings. That said the bar was incredibly difficult to remove in the first place. P.S. the T3 spindles do indeed appear to be shorter than OEM so adding the extra spacer seams like a good choice.

Doing some housekeeping and realized my dumb 240z site was down. It's back up now for whatever that's worth.

APEX said they would have a set made up by friday but haven't heard from them. Added a photo showing the APEX control arm length issue. Other bushing is lined up and its about 1/2" short. Put the rest of the rear together so i could sit it on the ground with the wheels and tires. T3 r200 short nose kit and rear sway bar. Got my tires in so got them mounted and installed for some motivation. Since I am using 300zx rear drum ebrake. I decided to use a 240sx ebrake handle (since I have this combo in my 240sx). Modified the handle to fit in the stock Z location. Mounted the cable holder thru the floor. Made a couple small brackets to hold the cables in the correct spot. Adjusted and works great. Also added a couple photos of the brake setup.
