Begin lubing the front bushing bolt long before you decide to change them. Its held into the frame by a squarenut. The squarenut is only held into place by a shitty stamped steel cover, it bends out of the way when you put too much stress on the bolt (ie when its rusted a bit). These things are inside the framerail so they're near impossible to hold still.
Ive spun those nuts on all 3 capri's that I've owned. Lubing the threads on it with penetrant really helps out, and can prevent problems. On the ones that have come loose from the cover I've had to weld the stupid nuts into place, thru the tiny access ports behind the bushing. No fun.
