Pretty unlikely it was from nascar but may have been intended for the circle track though. It was used for drag racing before I bought it (got a great deal!). Its been drilled and tapped for a fogger system too, but I'm not going that far just yet. Tried to find some info on the net 'bout it and found that buddy-bar had cast some of these for ford. Didn't fiind much else though. Think I will take '37's advise and keep lookin for a cheap pair. Got a well equipped shop and I'm pretty handy sometimes.. BTW I never skimp on ignition, just to bad my DUI won't fit, its the best setup I've had for my Fords!! Thanks for all the help so far!
