Engine: Frost plug

[bruin]

I have to replace a leaking frost plug but I can't find the size in my book and I am not sure if it's the middle of the plug you measure or do you measure lip to lip? It's a 6 cylinder in a 56 flight hawk. Thanks

With a set of calipers measure the void that the plug needs to fit in. Napa stores may have a listing for the size in their old catalogs. someone will chip in with a size or part number. Rich ?? Lou Cote
