Hey! I know this isn't the "For Sale" section,BUT...I just got the November 2012,(It's the latest one at the store here,)"Truck Round-up".On page 3,second truck from the top,1957 G.M.C. Short Conventional Tandem-axle/seems to be twin-screw,since it comes equipped with "Dayton" wheels,suggesting extra-heavy-duty. E-mailed seller to send pics. If,and when received,I'll let you know. Truck is black and silver,like Shane's L.C.F.! If you go to www.autoroundup.com,there are several listings of "Bolts" for-sale,mostly A.D.'s,but about every "generation" listed here,from pick-ups to 2-tons. Plus...PARTS,PARTS,PARTS!
