I have a 93 4.3 Mercruiser balance shaft motor that take a 10 bolt metal cover. Not 6 bolt plastic. See Pic. Does anyone have or know where I can get one. I've looked everywhere online. All I get is, NO LONGER AVAILABLE. my block # 10224535. Help!
Done that already. GM part # for actual cover is 12523080. Per GM dealer, NO LONGER AVAILABLE. No parts supply store has a listing for this part. NO LONGER AVAILABLE. Always referred to 6 bolt plastic. Right shape, but will not seal. Surely someone has one of these. I have just been unable to locate them.
