Newbie 65 Dart suspension Question

Ok, so I'm well into the chase for the BBP disc brake front, and i think i know if some rear ends around too.

I looked into Spitfire headers, and i was pretty surprised to find that the dude who runs it has a track roecord that is ...less than stellar to say the least! I figured i'd contact him anyway see what the deal would be to get some made, but I couldn't find a website, or a contact number thats still in operation. Any other suggestions? (or spare sets of spitfires that you wanna offload :P)
