Full 1969 BCUDA Suspension Rebuild

I need to order a full suspension kit for my 1969 Barracuda. All the typical shops want abou 1,000$ for everything....There is an ebay guy, oldparts or something selling the kit for under 500 dollars including shipping. Anyone have any suggestions as to where to buy the kit?
