Yep, i had it backwards. The front plate holds everything in place and the rear plate is held by the 2 in bar and the top plate. The spacer that goes on the cam bore bar between the cam thrust surface and the front plate is 0.100 thick and has 1.978 in ID.

I forgot all about the threaded spacer tubes to take up the space between the front plate and the timing cover surface.

Ill try to pm you a picture of the instructions specific for mopar big block stuff.
