I am installing a McLeod hydraulic throw out bearing in my 64 what diaphragm do I use Raised or flat. Stock 309 bell housing and Muncie trans. Just worried that if I use the raised one it wouldn’t have room between the trans and fingers on the clutch no adjustment or worse rest against the fingers. If anyone has this info it would be great. Thanks

I should have said raised diaphragm pressure plate or flat diaphragm pressure plate. Don’t want to confuse anyone.

Most cars that had flat diaphragm pressure plates were made in the 50s. I suppose that a 4 or 6 cylinder Chevy II could have had a flat one though.

For the throwout bearing, the difference is whether you use a short TOB or a long one. If you need the short one, there isn't enough room for the long one. If you need the long one, there's no way a short one can be made to work.

The other half of this is if you have a flat diaphragm pressure plate, you should be thinking about getting rid of it and switching to a raised one.

Thanks Rick for the info.Raised is going to be the way I go. Much appreciated.
