V8 clutch problem

[bobscogin]

I rebuilt a '42 Mercury flathead V8 to put in 'my '29 rpu. The engine was out of a fire truck and had the flywheel which uses the 11" truck clutch. I bought and installed a 1935-1940 car flywheel in order to use the 9" clutch. I'm using a 9" Long type "stock" pressure plate and the mounting bolt holes do not line up with the holes in the flywheel. When I install bolts in one pair of holes in the three pressure plate "legs", the holes in the other two or off about half the diameter of the hole. Also, I would have expected the pressure plate to slip snuggly into the flywheel rim. It has clearance all around equal to about the distance it's off on the holes. Photo shows the problem. What's going on here?
