Learned something new
 

While inspecting my 35 coupe a little closer I realized I not only have 39 brakes and wheels, but the entire front suspension and rear end/ torque tube is 39-40 as well.
I did not know these were a direct bolt in, but I guess the frames were all the same from 35-40 so it makes sense.

The engine and transmission appear to be 40-41, side shift trans, column shift inside.

Bad part is I just got the radiator and grille off and the motors stuck.
Good news, I have a spare that's not stuck!

Something odd too, the right side exhaust manifold is set up for a "hot air" heater.
