Re-engineering I like that, I re-engineered , massaged, bashed my firewall for clearance. Can't even tell it was done, not that they were flat slabs to begin with.
Exhaust guy cut off the hangars then twisted big honkin' self threading screws into my frame to hold new ones. What a Dolt! Two of them promptly fell out. I had to drill the holes larger then weld two plates, with nuts welded to them, onto the frame rails to fix it. Should have known to get out of the shop when a woman with her little girl got out of a taxi and came into the shop, both crying. They had just had the brakes fixed on their car, five miles down the road the front right fell off. The guy behind the counter started to argue with her about it being the shops fault. What a Dolt! Another customer and I intervened on her behalf until the shop paid the cab driver and towed the car back to repair. Mean while Dolt #1 was savaging my frame rails.
When I have anything I need to attach to a frame member - I follow what the factory did with the '67 OEM traction bars. Rivnuts.
