Issues w/ '39 Synchro Tranny with Mitchell Overdrive

[SteveE]

Any ideas besides fabricating new parts or cutting my frame to make this Mitchell OD work without interference? Thinking a rod with a U-shaped channel to clear the frame and battery box or a longer shifter pivot arm linking the rod to the OD.

Running a '39 synchro top loader tranny while I rebuild my '30 tranny. The aftermarket Model A frame (I think aftermarket) appears to not match the Mitchell design. I cut off the left "rabbit ear" on the '39 tranny (two ears on the output near the U joint used for trucks in the day).

Issues:
- Mitchell OD shift lever interference with '39 shift lever and Mitchell OD shift pivot arm and
- OD shifter rod and arm cannot clear the frame or the battery box.
