    May require some fender rolling or hammer work. But otherwise they will fit.

They came out nice too. The welds were really good. I wrapped them in some new Goodyear Eagle F1 GSD3's 315/35/17. Let me tell you, these are some WIDE tires.

    I have a 98 T/A and run around 2k also with C5 18s. Not sure about the ratio though.

    You can look on the door options sticker and some of the codes correspond to gear ratio's. Guy's chime in here if you know what the codes are. Or jack the car up and spin the driveshaft, count how many rotations of the drive shaft it takes to turn the wheels one revolution and put that number to th nearest gm ratio. Like if it turns 3 and half times thats probably 3.42 or 3.55, and if its 3 and a quarter turns that probably 3.23. etc.
