Uh Oh...Exhaust Manifold Bolts!!
The job of converting from stock to Long Branch manifolds on my '69 Grand Prix has begun. I have 8 bolts to deal with, and they are 9/16". I removed 3 of the 8 bolts no problem, but the others seems smaller than 9/16"....but not as small as 1/2". These bolts are all original and seem to have suffered degradation over the years. I have tried to fit a 13mm wrench on the bolts but cannot loosen them. I am also trying to avoid stripping the heads.
Any suggestions?? I am hoping to complete this task w/o having to pull the engine.
