I wanna put these on my 84 c20. The wheel wells are out and it's mostly gutted. Will these fit over the frame and not hit the steering shaft and brake booster or will I need to modify thous? I'm ok with trimming and modifying to and extent.

Do you know if these would work on a dirt Camaro Street Stock with Dart Angle Plug Heads? The firewall is in the stock location. Either that, or do you have a suggestion on a set that would? I'm having too many clearance issues with bottom dump headers.
