well went and picked up my third square today, it's an 87 454/400 with dual tanks and cloth interior (actually in pretty good shape if dirty)
it's in alright shape the rockers and cab corners are shot and i have some rust repair to do in the upper door sills (yes above the doors, how rust got into the flipping roof i don't know) but aside from needing to knock surface rust off of the rest it's solid. so the plan for this truck is to make it a home for the 1 ton dually 4x4 drive train out of my second 88 (
