I've been researching this for a week to get the correct pumpkin. I have a open stock 3.3 differential with a 4 bolt flange in my 03.5 AT5 Sedan. Im going to factory 3.69 from a MT LSD Sedan 08-09 models and there should be no issues with driveshaft length or pinion shaft length or anything right.

From all the threads I've read. AT pumpkin housing on newer models won't fit correctly, same for the coupes and something seems different with the 07's and that 08-09 G MT Pumpkins will be the only direct swap.

Guys correct me if Im wrong
