BBC engine rail kit. Both plates are 21 1/2 in wide. The rails are pre drilled for the stringer bolts. No holes drilled for the feet. I know my stringers run narrow, but I’m sure with some 1/4 inch angle, could widen feet if needed, flywheel cover has scratches and dings, could be smoothed out and polished again. The rails, as seen, I started polishing but decided to just order whole kit for BBF. Can finish for a few extra bucks. 375 obo. Will ship on buyers dime. Located in Tucson will travel to phx to meet if needed. Message here or text/ call 619 459-one 593
