I know I said that I was going to have to ease off my spending for a while, but these were too good to pass up.. I got a set of 2001 Cobra seats on ebay, front and rear, black leather outside with light grey inserts. my question is, I know the seating changed from 1998 to 1999. I think the tracks are different. Does anyone know how big of a hassle it will be to put these seats in?
