I suppose everyone ran into the same thing I ran into. Two of the 3/8 bolt holes overlap. Some step the sizes down some slot the bolthole on the SB mopar bell. I had the top hole in my aftermarket bell and just did away with the 10&2 O'clock positions on the mopar bell.

The only real dislike I have is the 7/16" bolt that goes above the starter next to the dowel pin. The corner of the R5 block is in the way. I have a 5/16" hole tapped in the plate with a bushing screwed in the tranny. The back of the tranny milled flat to run a 5/16X18 in from the back. IMO if the adapter went behind the starter this 7/16 bolt that is next to the dowel would not be so important. I have had zero issues with anything while running the car with the adapter.

It will just be less stuff if I change the pattern on a Reid Bell.
