Hot Rods Anyone know what this tool is for?

Thanks for that source! Sure beats the prices the old dodge parts guys ask for the bolts that attach the rear fenders to the bed on my 56PU. they use a similar bolt, just and elevator bolt with no square section. Holes in the bed are larger than the bolt shank, nuts on the outside, under the fender. Tightening the nut sort of dimples the bed, holding it in place with little to no protrusion into the bed area. Elevator bolts and a grinder to remove the square will do the trick.

 

haven't seen one of them in quite some time. i don't think they're made no more.

hang on to it if'n you can.
