(Its a 96 FWB.) I'm about to get the driver's side manifold bolts and gasket replaced at the dealer. They said the labor fot the driver's side is $145 and the passenger side would be about $300 because there is more stuff to move or something. I'm just doing the driver's side because thats the only side I hear a leak on. The back bolt is missing a head and they say I might have to get another head if they can't get the bolt out. Only 122,000 miles on the motor, do you thank its that bad? Should I get dealer GM bolts and gasket or something aftermarket? I;ve looked at JEGS and couldn't find any. Thanks!!
