Save anything off rusty 37, 46, rear axle, front axle, drive train pieces?

[malpais]

I'm cleaning out an old barn on our Ohio farm. Got some RUSTY pieces of flatheads, and want to reduce size of pile. Rear axle housings are pitted, as are torque tubes, shocks, front axles, backing plates, and drums.

I'm thinking of scrapping rear axle housings - keeping gears and axles?

Since front axles are pitted - scrap?

Some drums and wheels ( 5 wide and small pattern) are rusty but usable; some are trash - probably should scrap the whole mess?

Should maybe save the 37 engine and tranny - know they have been barn stored 40 years, so may be something usable in them.

Anything hard to find I should NOT scrap? Steering boxes, mechanical brake linkages? Got all I need for my 39 pu's in Colorado.

Thanks,
Gordon
