That's why.

I used Chevette springs at all 4 corners. I cut 3 coils off the front and 1.75 off the rear. It is at about stock ride height. It has a firm ride that doesn't seem to jar, but then again, roads are smoother down South. IMHO, try going with 16x7 instead of 15s. You have a better selection of tires.

The 72 doesn't have an intermittent wiper amplifier.

Search for wiper park. I think there is something on this site about that. You might have to just google that with the model of your car.

Read up on cleaning the wiper linkages. Replacing the wiper motor to account for the old linkages is like putting a new engine in the car to compensate for bad wheel bearings. Besides that, the dirty, sticky linkages cause the wiper motor to draw more current, potentially putting your wiring at risk. As for the jets, have you tried to clean them? I have shoved thin strands of wire into them to clean them out. Ultrasonic cleaning may work as well. You can disconnect the jets from the tubing to see if the washer motor still works.

Search for Zs-Ondabrain.

Flat-top carburetors - I'm thinking it's a 73.

Hard rubber usually means longer life and less traction. Unless your car is a daily driver, you can get away with a softer compound. Tread pattern will usually dictate noise. Then again, with a 40 year-old car, you usually get plenty of noise from other sources.

Check your u-joints to make sure they are not excessively worn and that all of the bolts are on and tight.

Here's the picture with the Rewinds. I need to take another to show the car with the new springs.

I like a firmer ride. With the stiffer springs and 16s, I do feel some bump steer when I get to the small drop at the end of the driveway. You can get a wider variety of tread compounds in the 16 inch tire, so if you want to improve performance and traction, you have more options. The Rewinds have received more than their fair share of complements over the Iron Cross ZX wheels that you can barely make out in my avatar. I think I have a picture of my car with the Rewinds in the "What did you do with your S30" thread.

I didn't have any problems with dust caps on mine.

The price is in line with what I paid for Rewinds/Khumos. I did pick up a rub on the driver rear with 215 tires. I can't remember the sidewall, but I think they were 55 or 50. I swapped out the springs/struts for Chevette springs & KYB struts. It will still rub a little on a big bump at freeway speeds, but it has to be a pretty big bump. I have to think that the rub is due at least in part to the 250lbs of dead weight behind the wheel.

It's easy to test the ignition relay with a couple of 6VDC batteries, some clip leads, and a multimeter. Let me know if you would like some assistance sometime.

Matt, bring it by my house. If the wiring was messed up too bad by IPOs, I can help you with the gremlins quickly.

I bought the seat foam from Banzai Motorworks, and I didn't use anything between the foam and springs. I didn't see a need to use anything.

By the way, I can even build a replacement relay if you need one.

Jeremy, do you need some help this weekend?

The rule of thumb that I have read is that you should use fusible link wire that is two sizes smaller than the wire you are protecting. For instance, if it is 10 AWG primary, you should use 14 AWG fusible link wire. Using the wrong gauge wire would be like putting in a bigger fuse because the smaller fuse kept blowing. You can find the size of the fusible link wires in the FSM.

Are you trying to find a new one? I doubt they exist, but just for fun, here are the Nissan part numbers with build dates: ASSY-PANEL REAR [table=width: 500] [tr] [td]Part Number[/td] [td]Start[/td] [td]-[/td] [td]End[/td] [/tr] [tr] [td]79100-N3650[/td] [td][/td] [td]-[/td] [td]7408[/td] [/tr] [tr] [td]79100-N4250[/td] [td]7409[/td] [td]-[/td] [td]7607[/td] [/tr] [tr] [td]79100-N4750[/td] [td]7608[/td] [td]-[/td] [td]7704[/td] [/tr] [tr] [td]79100-N4751[/td] [td]7705[/td] [td]-[/td] [td][/td] [/tr] [/table] Of course, you might get lucky...http://www.courtesyparts.com/panel-rear-p-425589.html

Jeremy, if you're having electrical issues, I think I know someone not too far away who knows something about Z car electrical systems...

Consider what you are doing with EtOH. You are adding extra oxygen into the combustion process. If you're high on CO, that might help. If you're high on NOx, it won't. If you're high on HC, I would think it would increase your CO.

Denatured alcohol is 100% ethanol, just with trace amounts of chemicals to render it non-potable. It is available at hardware stores. You could also get pure grain alcohol from the liquor store, but that's pretty expensive to run.

That's about 22% ethanol. Have you run a pre-test to see what your actual emissions are? The real fix may not be that difficult and probably won't put your fuel system at risk.
