Never paid too much attention to them over the years but now I need some information on the long style pressure plates. Looking at pictures of pressure plates that are advertised for cars the 3 fingers just have "tabs" on the end that ride on the throwout bearing. When you look at pressure plates advertised for trucks the ends of the fingers are hex shaped. My question is "Can I use the pressure plate with the hex shaped fingers in a car"?  Anyone ever try this?

I've seen both versions for trucks. It's just different methods of doing it. Either should work for you as long as the pressure plate is for a car.

What you are describing is the Long style pressure plate (with the adjustable bolts at the fingers) versus the Borg and Beck style with the flat tabs.

Ford used the Long style in the cars up through 1948 and then switched to the Borg and Beck style. The Long style existed longer in the trucks, I don't know for how long. There is a difference in the geometry of the pressure plates, as well as the external linkage and should be matched to what was correct for the vehicle when new. Other wise you won't achieve proper clutch operation. Also the Long style has a different bolt pattern than the Borg and Beck pressure plates, so you would need to have a matching flywheel or have your's re-drilled.

There are Long styles with and without the adjustment screws.  My guess the non-screw type is a cost saving move.  I have used both types interchangeably.

Only Mercurys used the Borg and Beck style pressure plates. This gets confusing because a Y-Block flywheel for a Ford is different than one for a Merc.

As with most lessons, I learned this the hard way.
