Try Fusick Olds for some parts, Rare Parts has suspension parts-buy on a commercial account for good prices-web site is a little confusing so call and they can walk you around, Shocks 2 Springs has shocks and other stuff, various suppliers for new springs including Detroit Spring, you can re-line your shoes, check other threads for suppliers on those projects. Search field is at bottom of page. Kanter Bro has alot of parts but as said above, they are pricey and IMO the have an attitude.
