Thanks for the pic. Mine have 87k on them but were probably damaged when I took her out of 10 year storage.... Still waiting on another response. Will be in touch.

Thanks,

Re: WTB: Clutch & Pressure plate for 1991 ZR-1

Thanks Jerry. I expect I'll be going with your RAM conversion kit. The reason for trying to stay OEM is the potential noise issues. This car has no mod's and is not raced. It does get some lively...

Re: Clutch replacement (or can I get it rebuilt?)

Re: Clutch replacement (or can I get it rebuilt?)

Thanks for the advice. I don't have a facility where I could do it myself so I have to use a shop. I'm talking to Precision Motive in Hayward at this point. I've no intention of going near a Chevy...

Thanks for the reference. I've used parts from Jerry's gaskets before. I see you're not too far away from me. Where would you go to get this work done?

Clutch replacement (or can I get it rebuilt?)

My shop has determined that the pilot bearing is about to give up. They plan to install a replacement clutch. It doesn't have a dual mass flywheel so they expect the gearbox will be noisier. ...

Re: clutch/gearbox screaming at me when I change gear

Thanks for the feedback. Unable to do this myself so have to find someone trustworthy in NorCal - or drive it half way across the country to one of the experts.

WTB: Tire pressure sensor wanted - just need casing - any year

This one has a tan colored housing. Doesn't need to be operational. Any wheel OK but RF would be ideal. Also any year or color.

Re: 90 ZR1 parts for sale

It's blue. My one got damaged - just broke the plastic cover - during tire change - so I can take any part with a cover and change out the innards if I have to.

Cheers,
Don
