I am new to this forum, and was sent here by a Ford buddy, also with a huge T/A racing habit. Personally, I'm into the AMC aspect of it, but I grew up around Chevrolets, and currently my brother has an old CenDiv 69 Camaro. I have a little input on the wheel topic, as I currently have a set of the American six spokes (also heard them referred to as TA-70) currently sitting on my Javelin streetcar! They've been in my family since 1985, and were originally 5 x4.75 but were "opened up" for the Ford pattern way back before we knew better. I have NEVER been able to find a marking on these wheels anywhere, but they sure spark interest to folks with an eye for detail. I'll try to add pics later. Oh, one of the last pictures above shows a Minilite with the "plugs" in it....more than likely from a 70 Penske Javelin.
