It's actually information from Novak adapters. They sell bearing retainers that fit the Chevy bell and Chevy- Ford pilot bushings..

From Novak's description
"Transmission Front Face Bolt Holes
On the front face 1966 and newer Ford four-speed transmissions, the upper two mounting holes are each about 1/4 of a bolt hole off from the upper two holes in a GM bellhousing. If the holes in the Ford transmission ears are filed to be slightly elongated, they will match up with their mountings to the GM bellhousing. It may be recommended at this point that you test fit the transmission to the detached bellhousing, which will facilitate the next step.

On the lower front face of the Ford transmission are two ears that, if stock, are undrilled. The lower left ear can be drilled to easily match the hole in the lower left of the GM bellhousing. The right ear can then be drilled. It will not meet up with any hole in the GM bellhousing, so it is necessary that you drill and tap one to match. Use the same size bolt as you do for the other three. If you are not equipped with the tapping tools or the disposition to tap a good, clean set of threads, you may take this to a machinist as well. "

My transmission was sold as coming out of an '87 F-150 so it should work.. I have a Ford 351/400 4spd bell I can check to see how far off it really is
