On my carbed SBC I removed the vapor tank and sealed all of the ports on the tank except the fuel pick tube and one port on the top of the "bulge" part of the tank. I ran that one vent line to the neck of the filler tube so air could escape as the tank was filling up into the "bulge" part of the tank.

If the tank is completely sealed, a vacuum will develop as fuel is drawn out of the tank. To prevent the vacuum, I drilled a very small hole in the filler cap.

Other consideration: with the vapor tank removed, do not top off the tank when filling up. On hot days the gas will expand and run out of the cap. Done this for 20 years with no problems.

Most likely a bad ground in the brake light harness at the back of the car. Pull out the rear panel and look for the ground wires and clean up their attachment points.

Also could be a dirty lamp socket. Pull the bulb and check the socket.

Suggest that you down load a schematic for your car. You are going to need it as a Z owner. Ditto a Factory Service Manual (FSM).

This is interesting. I pulled the R200 and half shafts from a 78 280Z, replaced the U joints and installed the R200 and half shafts in my 240Z.

Are you perhaps thinking of the driveshaft?

Take the half shafts to a drive line shop.

The strap is no longer required. The stock rubber differential mount you replaced would flex and rip apart eventually. Nissan installed the strap to keep the nose of the differential from pitching up under load.

For normal daily driving the solid mount works well. But the racers have reported that under hard driving the front cross member can crack and/or pull the center bolt through the cross member. I installed solid mounts in both of my Z cars 20 years ago and have not had a problem.

Cars present us with lessons. The lesson is repeated until we get it and then we get another lesson etc etc.

Just to be certain. These are the bolts you are working on:

Was hoping the mount swap would fix the clunking in the rear end. Just got the car and This year I just need to keep it in running / driving condition until next year when I can actually start restoring it.

Thanks for the replies. I’ll update the thread on how things go.

That solid mount you are installing may require longer bolts anyway.

Why not just remove the differential from the car and apply heat to the nuts?

July 25, 2019

You need more leverage. Use a 2 ft. long pipe as a lever i.e., put the pipe over the wrench handle to extend the length.

For example, I couldn't get the nuts on the stub axles to break loose. Tried an air impact wrench. The nuts wouldn't budge. So I got a 4 ft length of pipe and slipped it over the handle of a 1/2 drive ratchet wrench. The nut broke loose instantly.

Did you install the clutch disk backwards?

So if you turn the ignition switch to "run", pull the wire that connects to the temperature probe and then ground the wire, the temp gauge should go all the way to full hot.

If, while performing this test, the gauge bounces around, then there is an issue with the sensor wire or the gauge. Could be loose or dirty connections.

These links may be of some help:

Make model and year of the car?

Any modifications to the car?

Stock gauges?

Describe what happens to the temp gauge if you ground the wire connected to the temp sensor.

Additional Comments: a) Viscous Coupling LSD requires special splined half shafts - b) 84-87 R200's can be used in earlier cars, but require modifications they are not direct bolt in swapable to 240/260/280Z/280ZX's c) 84-89 R200's used a 12mm bolt in the ring gear - earlier R200 used a 10mm bolt in the ring gear, so you can not swap Gear Sets with the older R200's

Steering rack parts have been NLA for many years.

So called "rebuilt steering racks" also need those same NLA parts.

Always ask the dealer if the rebuilt/new rack actually has new parts in it.

If you search HybridZ you will see this topic was beat to death years ago.

If you find the parts you need post the supplier here for us.

What you have here is known as a Kluge: a collection of ill fitting parts forming a disgusting whole.

Looks like the PO used hard lines that were too long. To get the lines to fit he took up the extra length by coiling the hard lines.

The lines are not anchored correctly. Get rid of the yellow zip ties and do it right.

Replace the hard lines with stock lines or make your own.

If you are not up to making your own hard lines find a shop or web site that can make the lines at the correct length.

Note: the fittings on Z cars are all 10 x 1.0mm double inverted flare.

Well the Wilwood MC is in and.... still the same problem. Now I am wondering if the problem is the POs crazy brake lines coils they put in the lines for the rear. I will try to get a picture later.

Coils?

With the one inch MC you will notice that it takes more pedal force to stop the car. If you are going to larger calipers on the front then you will be all set. Even with the one inch MC you may still notice longer pedal travel before the brakes engage after you install larger front calipers. It is kind of a domino effect when modifying brake systems.

I bought the book from amazon for $25. It will be here tomorrow with free one day shipping. Amazing.

I would do the cardone replacement but I am having a hard time finding a master cylinder that is an early style tandem with the large reservoir in front.

Some after market master cylinders do not have the large reservoir in front. As long as the master cylinder is correct in all other aspects then it doesn't matter. You can always swap the front reservoir from the old master cylinder onto the new one for a "stock" appearance.
