I'm getting ready to install a P/S unit on my '69 Z28 which has headers. I will need a spacer that will go between the first header bolt and the pump bracket. Does anyone know the exact length that I will need to make the spacer or can I purchase the spacer at some part store? Thanks.

i just bought a power steering bracket adaptor for use with headers. It was 25 bucks and it eliminated the need for any type of "rigging". here's the ebay page it's on so you can check it out http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=597608009&r=0&t=0
