tti header clearance problem

I had to do all that too: move engine/trans, shim, shim some more ,shorten stud, clearance grind the castle nut, dimple the pipe and finally switched to 73up draglink.The dimple in the nickle plate has not rusted though in 15 yrs. However after 5 yrs the collectors developed multiple rust-throughs on top where the pipes enter. I was not impressed. They were $495 CAN at the time. I could have bought 5 cheapies. But TTIs were above the centerlink which was what I needed for my driving style,at that time. I have, since then,settled down, some. After repairing them, they lasted a few more years. They have been leaking at the collectors for at least 4 years now. I have been too lazy to weld them up again. The car is no longer my DD.
