The yard I bought it from looked in the Hollander interchange book (remember those?) and it was a direct fit according to the book. It went right in my 69 GTO with no changes whatsoever, still had the 2 spade connector which I never hooked up to a switch to get the advantage of the SP converter.
My car had 4.33 gears in it, roller cam, headers, etc, it really didn't need more torque multiplication for a street car with L60 14 Daytona bias tires on it, so I never got serious about hooking it up. Years later I wished I had at least tried it just for grins and chuckles.
