Raco GTP with Skellenger Rear?

[Mike Casey]

Hey guys, I have a Raco GTP car with a setup in the rear that looks like is for a skellenger rear end. The stock gearbox will not fit since its so big. A skellenger fits perfect but I am missing whatever it takes to mount it directly to the motor. The second picture is what I think it should look like. Anyone seen one of these setups before? I know it was not a homemade job because its just too nice. Plus I have seen more of these rear brackets around!
