Default 4L60E v. T56

I'm looking to see if anyone knows if the 4L60E and the T56 have the same mounting point (at the transmission crossmember) given everything else the same. I can't seem to find any info or dimensions through searching here and other forums of either 4L60E or the T56 to verify that they both have the same mounting point. I'm looking to find a crossmember or bracket adapter to fit a T56 into my C3, but no one seems to make one for the T56. All I've found is mounting solutions for autos, including the 4L60E. I don't have the tools to fab up my own mount, so I was hoping for a more bolt in solution.

So does anyone know if they are the same?

The T56 Mount is going to be farther toward the Rear in that car from where the old 700R4 Mount would be. The T56 Mounting Point is about an inch farther back than that of the LS 4L60E. You may have to make something up, or have one made.

I was afraid you were going to say that. I was really hoping mounting flange to trans mount was the same dimension between the two. We will just have to see then. Thanks!
