headers

You are going to be limited to TTI's or Doug's for under-chassis headers, Mark. The other option is the "Spit-Fire" header......if you can find a good set. I understand Laysons is the only place you can get them now unless you can find a set on EBay. Matter of fact, check if both sets of under-chassis headers will work with the 727. One of them is, I think, 904 specific.
