Gasket: Diff 10 bolt various 68-72 (w/Scallops)

GM Style 10 bolt gasket - with scalloped sides as shown... scollopes mean the sides between say 8 & 10 oclock or  2 & 4.. curve IN..

     Mainly used on GM A & B, some G bodies ( early 70's Impala etc..plus GTO, Chevelle, Cutlass). Found in 67-69 Firebird.

LOOK AT HOW THE GASKET SCALLOPS IN ON THE SIDE OR not.. on yours to know the difference in the 10 bolt gaskets.

This one often also referred to as a "12 bolt" diff internally but has the 10 bolt inspection plate.... so do match it up exactly 

If unsure.... check pattern as shown before ordering.
