My mechanic is not only a part replacement body. He's one of the most perfectionist person I know. Of course he can easily modify the repro bracket, but he much prefer install an original part with a perfect fiment without any modification required.
After 2 repro brackets with the same problem, I (and he) we're wondering if the problem was only a repro part poor quality, or maybe something else, like wrong manifolds. I taught maybe other people had the same issu with this specific part.
I'll look for an original one on eBay.
