Default Update 1937 Transmission with 1939 Gear Set Question

Hi All,
I have a question about updating a 1937 transmission to 1939 gears. Do all the gears need to be changed out? Or just the main gear with the synchro along with the shifter tower?

Thanks,
Denny

If you have a '37 trans with a 28T cluster with all helical cut teeth, a helical reverse idler and a 29T low/reverse slider gear on a 16 spline main shaft you can reuse those parts. Use the later 16T input shaft, the later mainshaft, later synchro unit and the 22T 2nd gear with a pressed in bushing to do the conversion. You will also need a shift top with the 3" fork.

I did this conversion on my 37 about a month ago. I called Mac VanPelt for his advice and parts needed. Best customer service I've ever received.

The shift tower can be used. The double detent is preferred but not mandatory. Mac VP has the reproduction 91A type front shift fork. Get a copy of Mac's book while if your at it. You won't be disapointed.
