Dennis, I just looked under my G50 car and took some quick measurements. From the part line shown in the photo, the G50 5spd nose cone housing is 4" not including the actual shift rod. There is an additional 2" space between the front of the housing and body. Looks very possible, though I'm not familiar with the structural integrity of that area. Looks like you could cut the sheet metal and rebox it in to fit the new tranny. As far as the transmission mount is concerned, I wonder if it would mount at the second arrow? Looks to be about the right spot.
