I had a guy wanting to trade me a cobra kit car (in pieces) for my 70 XR7 Car. i knew my car was one of 35 built with a 428cj and a 4speed tranny from my Marti Report. but my car came with AC so i had Kevin Marti do a search and tell me just how many of those (35) 428 4sp. Xr7 Hardtops came with AC. we'll i got my info yesterday and there were only three. So i think i'll keep my cougar.
