WTB-Crankshaft plugs - ZR-1 Net Registry Forums

All,
Have come across a problem with my crankshaft. The press-in plugs supplied by Bryant do not fit the holes in the crank. Does anyone have the factory plugs? are they NLA from GM?

Talking about the pressed-in plugs, NOT the threaded plugs. I *think* the correct size is 22mm, although the rear plug is bigger.

Thanks,
Todd Pepmeier

Shouldn't be too hard to find some frost/cup plug at an auto parts store or machine shop that'll fit properly. I wouldn't even bother to try & find the corrcet one's, per application. Also...a person doesn't know 100% that Bryant didn't change the size a hair either

You have to measure the hole. My Moldex was 7/8 + .002 The plugs come in + or - sizes. A local machine shop that does crank work can help you out, they did for me anyways. My set of stockers have no press fit to them on the Moldex crank.
