  1. Repair solution for bad turn signal switch

    It's simply a thin piece of steel. Cut the shape and drill the holes you need for the switch and the screws. My switch is still going strong; no issues. Good luck.
  2. Fabricated cowl screen for ram air hood

    Ill be there as a 'cruise in' car. Saving $35 this year. Thinking about racing Friday night before ZAttack? Music City Raceway will be open for Friday night drags. The cars will look better with some rubber on the rear quarter panels.
  3. The products work great to restore our 40+ year old plastic pieces. The texture coating produces a nice look while hiding some of the imperfections and missing plastic chrome coating. Sand smooth, plastic prep cleaner, plastic primer, SEM 39853 texture, then SEM 39033 color coat (charcoal metallic). Works great.
  4. Fabricated cowl screen for ram air hood

    Cowl side complete. This material works great!
  5. Posting to let everyone know of a very cheap option for grill screen or any opening you want to dress up or keep debris out. I used a gutter screen from Lowes to make a mini grill for the front opening in my hood. The screen is soft enough to easily shape and strong enough to be functional. It is even powder coated gloss black. Details in the attached pictures. Two pieces would make a nice grill. One above the bumper and one below. Note: The picture of the full piece is missing the piece I used for the hood.
  6. A sanding belt took care of it. Here is finished product ready to go in the car. It is in the 280Z now and everything works great. The 700r4 finds the right gear around town and on the highway to keep RPMs right around 2k. Probably 2700 or 2800 on the interstate in OD.
  7. Problem resolved! Cutting a right stub axle to be used on the left side worked great. I built a wooden jig to spin the axle under a chop saw. I used this setup to cut a cir-clip groove and to shorten the axle. Awesome results. I used two clamp collars to help guide the chop saw blade, this made for precise cuts. All I have to do now is replace the seals and install it in the car. 4.08 rear gears will be pushing my 280Z down the road. trim.11990050-DDBD-4E19-B3FF-4B71435BBC12.MOV trim.79395761-6E43-4FB2-8151-FC67A0514FF8.MOV
  8. Confirmed. Q45 carrier installed in 300ZX differential housing with 4.08 gears and Q45 input companion flange. The Q45 carrier shifts right (passenger side) due to the 4.08 gear setup. Because of this, the Q45 left side stub axle is too short! To overcome this, a ~.312 spacer would be needed between the ring gear and carrier. This isn't the difficult part. The difficult part is finding 10 M13-1.25/30 bolts to reach through the spacer. Because of this, I'm taking another approach. I am going to use a right side stub axle on the left side. This is going to require the shaft to be cut shorter. Note; you will need a right side axle stub from a Q45 that has 'full length' splines cut in it. You can see the different types in the attached picture. I will be cutting the center stub axle. The left axlet is the one that is too short after the carrier shifted right. The sealing surface length needs to be longer so that the shaft will fully engage the VLSD coupling and the support bearing. You can see that this surface on the center stub axle is longer. The surface is the same on the right axle, but there will not be enough splines once the shaft is shortened.
  9. The swap is possible and easy to do. Simply remove the VLSD carrier, axle stubs, and input flange from the Q45 carrier case and install them into the 300ZX carrier case. The Q45 differential I am using is a non-TCS differential. It is longer than the 300ZX differential, but the pinion gears are the same length. With the input flange from the Q45 installed on the 300ZX case, the total length is back to the original non-TCS length that I need. I need this length because I am replacing a non-TCS Q45 differently that is currently in my 280Z. The VLSD carriers of the 300ZX and Q45 are identical with the exception of the axle size they will accept. The Q45 stub axle is larger and this is why I am keeping the Q45 carrier. Because they are identical including the 13mm ring bolts, I should be able to install it back into the case just as the 300ZX carrier was installed. No need to setup the pinion depth and backlash. The pinion was never removed and I will place the carrier left and right shims just as I found them.
  10. OK, no replies or supporting information to my original post. So, I am going to attempt this swap and document it here. The top carrier is from a NA 1996 300ZX. The bottom carrier is from a 1994 Q45. My plan over the next two weeks is to transfer the 300ZX 4.08 gear set into the Q45 carrier; replacing the 3.54 gear set and improving 1/8th mile ETs. Stay tuned.
  11. By chance has anyone on this site changed the gear ratio of a 1989-1996 Q45 differential? My project is to change the 3.54 gears in a Q45 differential to the 4.08 gears from a NA 300ZX. The Q45 differential is currently installed behind an LT1 and 700r4 transmission in a 1976 280Z. Thank you to anyone who may be able to give me some information.
  12. Allows for easy access to bottle valve and visibility of the gauge. Make sure you run the blowoff (vent) tube through the floorboard.
  13. Another Dash Restoration

    Good luck Take your time and follow the instructions
  14. Another Dash Restoration

    Lost count on the hours...30-40 hours best guess.
  15. +3, add three gauges option (radio delete)

    Thank you. I restored the dash utilizing the Polyvance instructions, recovered the bottom portion of the doors and painted the bare steel at the top of the doors. Simply screw a trim piece (wood) to cover the vinyle to metal transition.
