Help with bearing and ring kit!!
So I am about to order a ring and bearing kit for my 258 I think that this engine is an 87 but not to sure I bought it used. My question is, is there a difference in bearings and gasket's from 1970-1989? I ask because the the place I am ordering the the kit from has 3 to choose from I can get one for 1970-1980 or 81-85 or 86-90. All the kits have all the same parts but there is a $5.00 difference in price between them. I don't get it.
