Ok, the quick rundown. Got an 03 Cobra IRS from ebay for my 88 Thunderbird. The owner had 3.90's in it but said he'd put 3.55's back in it for me; he also said it was just rebuilt with a 'master rebuild kit'. The guy claimed he worked at a big speed shop, outfitting cars for drag racing and that...
I was told by a seller that a moonroof motor assembly needing replacement is a very common contour problem. Is this true? I haven't found this in my searches yet. Thanks
