Can anyone recommend a good replacement clutch and pressure plate for my 1969 427 coupe that I am restoring. I want somthing similar to the original. I purchased one locally for my 1965 roadster and now have serious vibration problems between 1200 and 2000 RPM. I am now faced with removal and replacement for that car also.

Re: Clutch/Pressure plate replacement
Sachs, Luk, and Borg Warner make OEM equivalent replacement clutch kits, but a lot of guys use Centerforce. I don't know what you mean by "purchased one locally". Who is the manufacturer?
It would be a good idea to remove the flywheel, have it checked for flatness, then balanced with the pressure plate/cover and indexed to retain the balance when it's installed.
Beginning in '63 all Chevrolets used diaphram spring clutches, which were basically the same for all for all engines, but big blocks probably have more clamping force. I was always satisfied with the OEM clutches, so the OEM equivalent replacment clutches are probably also satisfactory.

If you want to go original, which I recommend, you don't need to get something "close"; you can still get the original pressure plate assembly used in your application from GM. It's GM #3884598 and it GM lists for $194.53. Unfortunately, the original clutch friction disc and its replacement have both been discontinued by GM.
Even if you use the above-referenced clutch, I still highly recommend following the balancing procedure which Duke mentioned. To avoid the "go-back-in" scenarios, the clutch pressure plate assembly, friction disc, and flywheel should be precision balanced as an assembly. In my opinion, this is CRITICAL. I would NEVER install these components without having this done.In Appreciation of John HinckleyComment

Re: Clutch/Pressure plate replacement
Duke, I really don't know what was sold to me. I went to the local clutch and brake re-line business that has been there for 50 years. Told them what I needed and they pulled the parts off the shelf. None boxed. They did re-surface the flywheel and balance however. This will be the third time I've had to remove the tranny in my 65 in the last 3 months. I just don't want to make the same mistakes on my 69 now in restoration.
Thanks ArtComment

never balance
as a assy. to start,balance the fly wheel by itself first then balance the clutch on the flywheel. this way any time you change the clutch only the clutch will need to be checked for balance and this can be done without pulling the flywheel again.Comment
