Wow, great shape, as said love the patina. Consider just cleaning up and sealing and keep the look. Looks like you've got the jump on rebuilding the tranny and engine, nice job. beautiful PU. Love Grampa's Merc. too, real beauty. Looks like he really took pride in the build. didn't see any reference to your '36 having an engine update. Engine looks like an 8BA?

I believe 1936 had an engine designation #68 21 stud 221 with cast in bell housing.

Yours has no cast bell housing & newer distributor. I like the 8BA, better power a little easier to work on. Distributor not as cool as the Dizzy but much easier to play with.
Best of luck with a great looking Ride & welcome to the Barn.
