was wondering if anyone could help me out with a timing chain cover for a 1970 350. i was replacing the chain and after i cleaned off what appeared to be all 40 years worth of oil on the old cover, and noticed that someone had over-tightened one of the bolts and sent a crack running quite a ways in it. just looking for a decent one to get me by till i finish the bb. hopefully someone close to me near the madison, wi area. thanks! josh
