On the AM style conversion the reverse lockout is moved to the forward position - I machined up a plug to fill the old hole in the back as I too had clearance issues when I put the skip shift solenoid in there (just to fill the hole).
I welded a bit on the socket part that catchs the reverse lockout pin when its extended - Wish I had pics - would make a lot more sence.
EDIT - The master beat me to it.....
