Guys. When posting those links, just remember to add a space behind them after pasting them in. Most of the time, that’s all it takes to get them to work. I fixed the one above.
Kevin. I have similar sets of 180° headers for FE’s with one set being for a Fairlane/Mustang chassis and another set being for the ’60-64 Galaxies. It’s hard to say exactly which chassis your particular set of headers fits looking at the pictures but I’d take a guess that they would be for Fairlane/Mustang chassis based on the dinging that was done on the tubes which to likely give some additional clearance at the shock towers.
