for those interested, the answer in yes.
Found a 2012 5 speed box at local scrappy, done 10k miles. took my old casing down to compare and looked extremely similar. took the gamble and bought it.
just finished a road test and all is well. 1 bellhousing bolt which goes to the sump doesnt line up but all others do, and drivers driveshaft mount to engine mount needs a little modification to fit. otherwise is a direct replacement.
This now leads to the possibility of using a t5.1 6 speed box for a 6 speed conversion, going to keep my eyes out for 1.
