Their is a 4 piece style(usually found on Cudas) and a 3 piece style(usually found on gran coupes)but doesn't always fall true.Talk is going on about that on Moparts in the resto section.I think the 3 piece is anodized aluminum and the 4 piece is stainless.I am looking for a useable 4 piece set for mine,I am just cheap and it's not a pressing issue at this point.
