Adapter Kit.. ‘39 trans to A/B engine.

[GeneBob]

I called Van Pelt about swapping out the gears/synchros and the person I spoke with said it would be very expensive to buy the whole set from them. He suggested finding the 39 or the 40-48? gears and synchros in a trans, then buying the parts that need to be replaced from Van Pelt.
The attachment of the Model B trans is different than the Model A so you have to match the flywheel housing/oil pan or something like that.
