Re: Bad clutch
Albert
Make sure you have the rear axle supported on jack stands or the rear housing will hang down and slightly forward causing the driveshaft to appear too long. Measure the driveshaft in your 70 it should be the same length, or real close to the 69 driveshaft. Had the same problem with my 70 Chevelle, jacked up the year and the driveshaft fit perfect. You should have 3/4 to 1 inch of slip at the trans yoke.

Re: Bad clutch
Jeff, I use the Centerforce II..very happy with it, light pedal pressure and so far good grip. I am much happier with it than the heavy pedal Hays I had in it.

Re: Bad clutch
Kevin, thanks I'll try that, but if anyone has a 69 shaft out that they can measure that would help out alot too. I bought this shaft separate from the car so I am not 100% sure it is the correct one. It fits and looks right but seems to be 2/1-3/4 of a inch too long.

Re: Bad clutch
Al,ask the shop that is doing your driveshaft work where to measure from..On the car.. They will adjust the length of your shaft accordingly. Most have ther own way to come up with the dimensions...It's usually whatever works for them. I've built a lot of driveshafts this way....

Re: Bad clutch
i hate to say it but i am having trouble with my hays 11" set up also. i used a good used flywheel, had it surfaced ground and bought the complete kit. also installed new pilot bushing. this spring i noticed a "grunt" sound about halfway thru the release. now it is doing it more often, the other day after a 25 mile drive and 4 hour cool down i started it as usual and pushed the clutch in and it sounded like metal to metal loud squeal. it continued for a few gear changes and was then gone? i got home and got it raedy to put away and it was back to normal. i am almost afraid to take it all apart and not find the root cause for problem.

Re: Bad clutch
The only difference I could see was the TO bearing that came with the Hays set up was almost 3/8 of a inch taller than the C-force one. Actually made the release arm sit too close to the bell housing. Something was not right there and now it is gone, thats all I care about!!. Ran the valves today, re-checked the timing..a little cleaning up and I'm ready for Collinsville!!!.

Re: Bad clutch
found the problem with my noise today. it had nothing to do with the hays clutch setup. some dummy forgot to grease the pilot bushing (ME) before installing trans. i thought sure that i had done that too. well it was a cheap fix (new bushing) and a good reason to double check yourself on the simplest of matters. dennis
