This is a set of 2(1 Pair) of Pioneer USA NOS Steel Rocker Shafts. Made of 1021 Carburized Steel, as are the OEM pieces. Ford  interchange number on these is B8A-6563-A . Included are 4 Cotter Pins to be used with these.. I used to keep hundreds of these in stock, but am now getting down to the last few sets I have. These are NEW, not used or refurbished. These were bought long ago, before 2000 so I am pricing them accordingly. IF you are rebuilding your Rocker Assemblies, look at my auctions as I'm selling lots of small parts used for that purpose. FREE SHIPPING via Priority Mail on these, and supply is limited. Payment required within 10 days of auctions end.  Please see my other auctions for MANY MORE Ford HiPo parts. Questions?
