been on the look-out for a clean short box square and I settled on this '77

stripper model, no AC, 250-six, 3 on the tree, manual everything. minimal rust, mostly in the rockers like usual. looks like someone lowered it a bit, but I dont know how or how much.
eventually it'll get a chinese turbo'd 5.3/4l80e. Just waiting for the time and a good deal on a converter.
