i'll make ya a deal. go into the "Mopar clubs and Member Registry" part of Moparts and register your truck(or PM me)in my registry. i'd love to have the info.
as for my truck, it's a 77 D150 Adventurer clubcab shortbed 440/727. i have over 400 trucks listed and this is the only 440 clubcab shortbed i've seen. of course, i have dynotune to thank for it.
