'36 vs.'39 Ford frame question?

What are the differences? Can a '36 go directly on a "39 Frame? If not, what modifications are necessary? Thanks.

 

'35 to '40 are the same.

 

front crossmember is different

 

the car in my avatar is on a `40 frame. a few holes were different and the radiator mounts had to be changed

 

NO, the radiator tabs in front of the front crossmember are different.

36's don't have the sidemount boxes do they? Should be easy to remove from the later frame though.

 

i have a 39 frame under my 36. no problem. motormount cushion holes are a different size so i just got later cushions. no big deal. have both at the shop in tacoma, pm me if you want to come by and compare them...

 

Thanks fellas, just asking for a friend, all good information.

 

Its the pickups (all years) that don't have the side mounts
