Long Tube Headers
Jun 11, 2019
GREAT DEAL
I put these on a 1974 Nova 350 with A/C and power steering. I chose to delete the lower A/C bracket which was really not needed anyway. Everything fit as it should with no exhaust leaks. All the hardware was included and worked. I have had low priced headers before and never had much luck until now.
