I'm not to concerned about the steering gear-box, (mine does have power steering though, again Hedman says they will clear that), what I am worried about is the A/C evaporator cover that is attached to the firewall on the passenger side. It looks to be very tight. I have a set of Hooker headers with 1 5/8" primaries that I ran on a '68 Camaro I had a couple years ago and they WILL NOT clear. My other car had the A/C evap. cover removed many years ago so those headers were most likely for a NON-A/C car. I guess it will come down to "ya spends your money and takes your chances" saying I have heard for many years.
