I have a posi 3.42 on my cutlass. Has a bent axle so I was thinking about fixing it( cost $250) But.....was also thinking about getting a new heavier duty rear end with 3.73 which would cost like $1600. Is it worth doing or put the money into something else? Has a built 403 and stock 200r4 transmission. Not a drag car and won't put on the track. Just a good running car for fun on the street.
