Sorry. We are buried delivering the 50th Anniversary 427's to Shelby and finishing up their 50th Anniversary Daytona Coupe for SEMA.
The rod end goes into a 1/2" hole we drill into the bell housing.
PLEASE NOTE!!!!!
I have NEVER seen a bell housing fit properly on an FE block! There isn't enough relief around the 7/16" holes to move the bell housing up when you dial it in. The radius on the bell housing hits the bolt head when you tighten it down. Some of the holes don't have any clearance at all.
We finally gave up and wrote a CNC program on our mill and cut all the holes to 1/2" (so the bell housing can move up) and then relieve the radius so you can put a washer under the head of the bolt.
In the same program we drill a 1/2" hole that the rod end goes into that acts as a pivot for the throw out arm. It is a pretty cool set up.
Happy to answer questions. Sorry we are so hard to get a hold of.
David
