Sounds like it fitslike every other aftermarket part,Ie;not at all! Lol,many is the time I have tried to bolt on an aftermarket whatever,only to discover it needs work first..
I paid extra at the machine shop to "Fit" the girdle. I assure you that is the "Last" time I use that particular shop! The sealant not sticking to the girdle is on me but the rear main seal retainer is on them. They lost my original girdle so the one on it may not even be what I paid for??? It looked the same!
