I just noticed that Motorsport is selling a BRE-style air dam in fiberglass or carbon fiber. I'm seriously considering one of the fiberglass dams. How much work is it to install one of these? I'd imagine it involves some measuring and drilling.

Vollmer Service Center 3820 San Pedro Ave San Antonio, TX 78212 (210) 732-2201 They did a lot of work to my '77 and know Zs well.

I just had the car in for a checkup at the shop that rebuilt the A/C. They determined that there's an electrical problem -- the low pressure switch isn't coming on because it's not getting the juice it needs. So somewhere in that car is a wire, connector, and/or harness that's shot. I imagine it's somewhere under the dash. Pity I can't just buy a new dash harness and install it.

"Blew up" is about all I need to hear, FastWoman. I think I'll stick with the R12. I'll ask the shop if they'll fill it with Freeze 12, maybe that'll save me a few dollars.

Thanks for that info and link, Steve. My car's A/C was rebuilt a few years back and is still using R12. Is there any good reason to have it converted to R134? I ask because this will come up when I have the system recharged when the pressure switch is replaced.

Uh-oh. Just paid a visit to my local Nissan stealership, and they told me that part is no longer unavailable.

That's good to know! Do you sell a spoiler that does not have the ducts?

With the car off and the leads disconnected, I put my multimeter on the under pressure switch and it failed a continuity test. So there's my problem. Now to find a new one and start saving for a few cans of R12!

I've never been crazy about the blocky air dams sold for the 280Zs. I've always preferred the blade-like air dams, like the ones BRE used on their 240Zs. Check out this picture. It's from a 1976 issue of Hot Rod magazine, and it depicts a '76 280Z with a BRE-style air dam. So I know they were once available for the 280Z. Anybody know where I can get one?

Thanks for all the good tips and info, gents. I'll hit the books and get under the hood this weekend.

They're a good shop. They just didn't know what to do with a car that's 32 years old, and were honest enough to tell me. Thanks for the suggestions. I'll double-check and/or replace fuses next.

My air conditioner only blows hot air. Contol panel is set to AC, but no cold air -- and I don't hear the compressor kick in. The car's air conditioner control panel was replaced about a year ago (apparently it was the last OEM unit left in the US). There are no blown fuses. Today I had the cooling system checked out by professionals and it passed all tests -- freon pressure is good, and the compressor comes on when given power from battery. Any ideas?

Call Vern Vollmer's shop at 210-732-2201 -- they've done a lot of work to my '77 and know the old Datsuns very well.

Thanks for the offer, but I think I'll just try to find an original driver-side mirror. This thread has been informative. Thanks a lot, folks.

Thanks for the pics. I was assuming that the passenger-side mirrors were, um, mirrored replicas of the stock plastic one-piece mirror on the driver's side, but your pictures proved me wrong. It's a shame Nissan didn't make those, they're really quite good-looking mirrors.
