Clutch Questions?
Hey guys,
I have a few questions regarding my clutch, and those that can replace it. First, the clutch on my 307 is an 11 inch. Will a 12 inch work with the fly wheel, if i replace the clutch and pressure plate? Second, if the 12" will work, can a 12" from like, a '95 Chevy, work in my '69? They're both small blocks...same bell housing..fly wheel...etc. Now, the explanation. I'm low on cash. my clutch is going to hell in a handbasket, to put it frankly. My dad works at the area salvage yard, and today a '95 Chevy came in with a good 12" clutch. he can get it pretty cheap, and save me lots moneys. (I know...I know...i shouldn't use a used clutch. but, gotta do whatcha gotta do.) So, ANY input would be appreciate regarding the situation. Thanks in advance guys. -Sam.

Re: Clutch Questions?
My 69 came originally with a heavy duty clutch setup and when I converted it to the lighter duty (got cramps in my legs) that had a smaller clutch diameter, I had to replace the flywheel, clutch and plate. The bolt pattern of the pressure plate was different on the heavy duty, larger diameter clutch and pressure plate.

Re: Clutch Questions?
Ah, thanks 68gmsee!
Thats just the info i needed. I'll order a clutch disc from autozone on wednesday then for my 307, and hope that my pressure plate isn't screwy. I don't think it is, just the clutch is so worn down that it's not grabbing good. thanks again. i really appreciate it. -Sam.

Re: Clutch Questions?
If you are looking for a used clutch, I have one I just took out.

Re: Clutch Questions?
I did this exact swap - my 67 250/3sp came with an 11" clutch & I was able to replace it with a 12" out of a new diesel by merely changing the throwout bearing, clutch & the pressure plate. The clutch dude who sold it to explained that the 10" need their own setups (flywheel, pressureplate, etc) but the 11s & 12s share the same flywheel, just a different clutch plate & pressure plate. i know its extra money, but ya gotta get the flywheel ground. the 11" left a bit of wear that the 12 will be bigger than. Its cheap - like 15-25 dollars.
