2001 Pontiac Trans Am

The LCAs slide into place, helped by the provided lube on the outside of the bushings, but the bolts cannot be fully tightened until the rear suspension is loaded. Since we are also installing subframe connectors, they need to be set loosely in place before the front LCA bolts are inserted (look closely and you can see how the front LCA bolt helps position the subframe connector end plate, near my right hand). Caution: The factory LCA bolts are not the same length. The longer ones (12mmx1.75x105mm) normally go at the rear axle connection, and the short ones (95mm) go at the frame connection up front; however, we found that with the added thickness of the BMR subframe-connector end plate, the factory front LCA bolts did not fully engage the nut threads to our satisfaction. As a grade 10.9 bolt of this size is virtually impossible to find at any hardware store, we ordered a duplicate set of rear LCA bolts at our local GM dealer (PN 22657681, about $4 each), and as you can see here, they're plenty long enough to work up front.
