What gear shift lever should we use?

[Mac VP]

The other issue with using the 81A-7222 shifter tower (1939 type) is that the profile changed from the slanted casting (32-35) to the upright casting (36-39). This puts the top of the later tower forward by about an inch. Thus, you’d have to open up the hole in the transmission sheet metal cover by enough to clear the front side of the 39 tower (and presumably you’ll want to close up the original opening to the rear). If you’re not doing a restoration, this is not a big deal and has been done thousands of times over the years.
