i went through this a little and got discouraged some. my bronco is, i think, and regular bronco with some stroppe accessories. someone lived somewhere near the stroppe shop and had them put on some of their parts. thats the most plausible answer, but its still possible it's for real. andrew at bajabroncos was great to chat with about what was the Standard stroppe, and also all the odd ones too. great info there. the dmv's from some states are helpful, and some are not so good luck there.
