@gts posted:You Are wrong too. The diagram is the GTS option List.
It isn't an argument to defend my comment that the diagram is a Group 4 parts list. What ever it is, it is. I just find it strange that a full roll cage would be offered for a street car rather then just a roll bar?
Considering that I suppose the philosophy of Detomaso was, "cash talks, nobody walks" explains a lot.
I would at least concede that the diagram is incomplete as compared to what we have seen on Group 4 cars, presuming that all of them were identical, which I kind of doubt anyway? That the Group 4 cars that I have seen, limited as that is, had rear braces to the roll bar to the top of the rear wheel tubs, or the rear deck lid tie downs that don't show in the diagram either.
I wouldn't accept the title of GTS diagram just because there are GTS decals offered in the list as proof.
In any case, Push is on his own to fabricate those clamps. I can't find any premade anywhere right now. Perhaps one of current the GT40 "continuation" manufacturers have made some available?
