1st set is a real good set of modified headers,not sure what they fit,I was going to try them on my Street Stock. 2nd set Shoenfeld 6 race old, overrail for a stock clip GM.I tried these on my Metric SS and with stock motor location front tire hit the passenger header(driver was ok). I would take 80.00 for both sets. Can send pics,located Central Illinois. 217-371-9418
