My 1970 dart swinger restoration

This car has Spitfire headers,they fit very well .The only clearance issue was the steering coupler rubs against the headder knocking the metal clip off of the seal on the coupler.They are hand made by a gentleman somewhere in Georgia.You should be able to GOOGLE SPITFIRE HEADERS and find more info.BEST FITTING HEADERS I HAVE EVER INSTALLED!!!!!!!!!!
