Today I swapped the axles and axle housings and they did interchange. Unfortunately the driven pulley is way out of line with the drive pulley. Too far to the left and is hitting the frame. Also the angle of the mounts is off so the driven pulley is too low.
The mounting bolts did line up though.
So tomorrow I going to pull the tubes and cut them. One an inch (guessing for now) shorter than the other. Then the flanged pieces will be swapped side for side and welded back together. This should move the differential over enough to line the pulleys back up. This will also allow me to rotate the differential to the correct angle. Getting this right is going to be a challenge for this guy.
Also had to redo the rear engine mount to allow enough clearance for the shift shaft. I was warned about this so once again the advice from the members here came in handy.
