So, after installing the replacement pressure plate from brewers....problem solved!!! My luck I would get the one defective one to begin with. ...............
Very good. Been there, done that. I got into the same deal. Years ago, I installed a factory 'Vette 10.5 diaphragm unit in my 340 in the 70 RR body. No, they did not come with 340s, LOL
I got the "one unit" out of hundreds that would not release. Of COURSE this is a change from 3 finger, so you think of "everything else."
Finally, sent it in to a local clutch and brake outfit who had a press to check it, new press plate, worked GREAT.
