Our '82 Monte Carlo has a situation where to get the RF camber desired, the rear bushing flange hits the exhaust manifold after being shimmed. Yesterday we melted the new poly bushings and created a very twitchy racecar (upper control arm shaft was flopping within the steel bushing housing). We run 200 laps so the heat is a real problem. I did not look too close but we may have rubbed a hole in the manifold and the exhaust was blowing directly on the bushing. I'm sure others have this close encounter on their metric cars. What is the best way to aleviate this? I was thinking of shimming up the right side of the engine about a quarter inch or moving the engine slightly left? I'm sure if we used a steel bushing we would cook out the lube so we want to fix it right! Any solutons?

Thanks,

Take your ball joint out weld the little holes shut grind them clean and level grind the big hole in closer toward the cross shaft( this moves the balljoint in ) set the balljoint back in the big hole and redrill your bolt holes paint everthing flat black or paint it with muratic acid and then wash it off in a half hour or so let it set out and will rust pretty quick. also grind the control arm off by the manifold a little . If you would put taller ball joints in the top you may not need so much camber .

We got some '86 Z-28 exhaust manifolds lying around. I'll have to check and see what they're like.

Thanks to all!
