just some food for thought, we just pulled my car apart because it was clunking pretty bad at idle, and found that the rear bushing was completely gone. I hope my drive shaft is straight still!
I order my bushings from corvette central for about $70 for the both of em. I called RPM and they told me that there was no difference in the bushings and that they were all made at the same place. I wasn't able to find those harder GM pieces. I'm putting those GM ones in, and we'll see how it goes. I didn't go with the billet ones because of fear of vibrations. I'll try to post pictures of the destroyed piece when we get back to working on the car. Its snowing in North Carolina LOL!

Alright can someone tell me the part number for the GM TT coupler. I agree that the GM one is harder and that the pics do not lie, plus I held one of the BMW in my hand not too long ago and they were DEFINITELY not the same material as the couplers shown on the right of this pic.

Thanks for your kindness and insight. I am really hoping for JUST the clutch package. I have had no vibration, rattle or noise except at the very beginning of clutch engagement. My only thought right now is getting at the pressure plate and disc for the first time. Chevrolet sure didn't engineer for the poor sap who had to work on one of these things. I will certainly keep you in mind. Hope you don't mind if I might call upon your expertise in the future? Thanks again
glad to help. yeah just keep us posted on any questions you may have. You do know you got to pull the whole rear subframe with tranny and rear end plus the torque tube to get to the clutch.

dude i did that soft rubber crap. Its no good you are going to tear them up! Save your money and time. They are all the same crap the BMW, the corvette central, and the jaguar ones. No good. Go solid and you'll be happy.
If you do the rubber ones try the BMW M6 they have them at the BMW dealers and the M6 is around the vettes power.

Yes I know, I got the Corvette manual inside the car when I purchased it. There must be a total of 1000 pages devoted to removing the clutch. A long way from laying under my '57 and dropping the trans on my chest. I have the exhaust and shifter out, I am just about ready to start attacking the rearend/torque tube. I am going to start on it tomorrow, it is supposed to be in the 20's---that is a heat wave this winter. Thanks for being there

just in case anyone cares, I called Corvette Central and explained that I just bought these bushings about 2 weeks ago(must have gotten the last couple before they sold out) and i was wondering if they would take these bushings back since they deemed them junk, and all they would tell me is that they had no problems with those bushings and that there was no manufacturer's defect. They said the only problem was that they had been back ordered
that confused me............
i'm not looking for a refund or something, but they acted like none of this happened. I'm going to give them a second chance, and will call back with those codes listed about in cajun's to see if I can clear things up.

I called them. They also told me that there was no manufacturing issue, only a normal back order. They said that those codes listed applied ONLY if they were listed in place of the estimated delivery date. Maybe it doesnt mean anything, I guess I just dont understand why it was included in the email if it does not apply. I think I might have jumped to a conclusion after reading the comments. Either way it does not affect negatively on Corvette Central since they are merely the vendor.
I did cancel my order and am getting my couplers from Gene at gmpartshouse.com

When being nice fails, do this. Ship it back with a tracking number and call your credit card company and do a claim. fax all your info as far as manufacturing defects to the credit card company.

What are you looking for? a free one? new or used? are you going to install it or just take some dimensions off it?
I can scan a coupler for you and send you the jpeg or even drop it into cad and get you some more accurate dimensions, but i can't do it right away.

I need help! This is the first time I have owned a Corvette. Have a '98, 6 speed with 54K. It has started to chunk/chatter when you engage the clutch from a standing start (forward or reverse). It is fine once it is moving. If you find the exact RPM you can eliminate the hic-up start. Most times it is just embarassing, like your first clutch. I assume PP and disc but have people telling me it could be TT bushings. How will I know? Is it an obvious thing when I get it torn down? Also, does the clutch slave normally give out to the point I should just replace it? Money isn't my strong point so I am trying to do as little as possible.
Thanks.
