Put these on my 64 gto, was happy with the fit, instructions say you may have to shim the frame mounts to make it fit properly but I only had to ding a pipe on both sides just a little, which I expected to have to do anyway, I've had some nightmare header fitment issues in the past with different vehicles, with how much i would have to smack em and bend them to fit, these just slid in nice and like I said just a small ding with a pipe on both sides, passenger side to clear a slight hump on the crossmember and a slight ding to clear the A arm bolt on the drivers side. Very happy to do only that for a very inexpensive but good quality header and not mention it's for a pontiac and not for something as common as a chevy

The fit was difficult. The motor needed to be raised . 2 bolts did not line up with the heads and required enlarging . The header interferes with the steering column lock rod.
