OK, here's a pic of the back end of a TS52. The radial mount measures 3 15/16" from outside to outside. Just to make it easy let's say 4" or 2" center of crankshaft to outside. If the "usable" ( I assume you are NOT counting the tri stock ) width of the firewall is 7 3/4" overall or 3 7/8" center to edge than that would give you 1 7/8" to move engine to the left to account for the right thrust.

This seems to be MORE than enough room to accomodate the radial mount. Am I correct ? The height might be another matter altogether, but I have not glued mine so if the mount sits too high I will just make a new firewall, the plywood they supply if I remember correct is not the best anyway.

As an after thought it is 6 1/8" from back plate to front of prop hub.
