Special thanks to forum member Articifer Tom who linked me to a 29 Chrysler owner who had a pressure plate for the 29 Plymouth in excellent shape. Should be in the mail soon.

But with this being said, at some point these items will dry up. I have found out much about these pressure plates and many of the venders that supply the rebuilds. Unfortunately you can't keep resurfacing them forever. The 4 cylinder Plymouth flywheel is flat so finding a modern equivalent doesn't seem that hard. You would think that this problem might have had a solution at this point but maybe the demand is to small to make the effort worthwhile. Might be an opportunity for some reverse engineering.
For those of us like Frank who love to drive their cars this pressure plate issue will come up again. I was told that the newer style pressure plate can be used in cars from 1928 to 1932. I think that's a lot of cars still on the road.
