New drivetrain???

So, after trying to test fit the mustang tranny, I have come to the conclusion that it won't leave me enough foot well room for the ol' 13 wides. A friend of mine has graciously offered to let me use the drive train out of his 1969 Datsun 2000 roadster. With a stock HP rating of 135 and no engine management software at all to worry about, it seems like a good idea.
