Default Re: Model AA Truck, whats it worth?

areas to check:

the lower bead on the cowl sides, the bead around the bottom back of the cab. These areas get rusted through often. Its possible it was bondo'ed up and painted. Use a magnet to check for bondo. Check the windshield frame for rust though. Body work is expensive.

AA fenders get really beat up. check the bead for repaired cracks, look underneath for welds, gussets of farm scrap steel, deep dings that are filled on top with bondo.

The engine compartment is probably a more reliable indicator of the true condition of the truck, as is the underside. Look closely for rust through underneath, cracked motor mounts. Check the engine closely for knocks, even compression in each cylinder, rear main oil leaks, good cooling (drive it up hill ).

On AA's, the cupped short shaft can be worn. Listen for a clunk at the back of the transmission when you go from reverse to forward.

The rear spring pivots were hardly ever greased and the brass bushings were very thin. Expect to have to repair them. If the outer washer looks off center from the pivot, the pivot is probably worn. Check the front spring shackles to see if they're worn through the hangers or bent from heavy loads.

It is a late 31. check the brake drums to see if they're cast iron (a plus). the indicator is a square lug on the outside edge of the drum where it rides next to the backing plate.
