I really apprectiate that. I wish that were the case as well. What do the transmissions weigh out at? I have lifted a 3 speed and it does not seem to weight any more than a head. I know 4 speeds have more parts (obviously) but how much more heavier are they.
I use Fed Ex to do all my "heavy lifting" under 70 lbs. They take heads and cranks all day long. In fact it is only about $40 to ship a head coast to coast via fed ex. I've done my homework in this department.
ANYWAY I digress from the topic at hand. I guess If I WERE to fit it under there I would have to measure the "pinion flange to axle centerline dimension" Joe mentioned.... I know getting a custom fitting driveshaft is a matter of FINDING the place to get it done.
I have a lead on a guy who might swap me one for one for the correct unit, but who knows how that will pan out!
