This is a new original 3.23 to 1 ratio ring and pinion set for 1953 Packard automobiles. The Packard part number is 902500. This set is a one year only item, don't miss out. The ring and pinion are covered in the original factory cosmoline and there is no rust on them. This ring and pinion still has the crumbling Packard box. See my other listings for more Packard items.
