I'm wondering if anybody here knows a good shop that will install my gears and posi unit in my Impala. I really haven't driven the car since I lost 3rd gear and I figure while I'm already blowing $$$ on it I might as well make it a nice build over the winter. Threfore I'm definitely going to need the gears and posi working to achieve my goal for 2008. What shops would you recomend me? I found 2 recomended shops but one is in Lake Villa and the other one is in Crystal Lake, I kinda want to go locally something less than an hour drive. I live in Bensenville and I do not want to play cheap. I want to do this right the first time. Is there by any chance a member here who knows how to install gears on a old heavy SS? :naughty: I've been quoted from $300-$450 for labor I'm just debating on what gears to go with 3:73's or 4:10's.
