I figured this should be under a new thread instead of Weber carbs and EFI:

I had a TVR 2500M, and still have some of the factory manuals. I looked into
adapting that rear into my TR earlier, but have been told by a couple of
people that the outer hub supports are too weak, and can fail. Plus, you
still have the TR6 style outer stub axle, and halfshafts, which is what I
shy away from. I will see if I can glean some information from what I have
here, but I don't recall having the alignment data.
DOES ANYONE OUT THERE HAVE ANY REAR ALIGNMENT AND TRACK SPECS FOR A
1973-1974 TVR 2500M?
Thanks for the response Bob. I had forgotton about the TVR, since I had
written it off as a dead-end early on, but it could be a start point for
what I want to do for wishbone design. I recall the whole thing was
adjustable on mine.
I may just start out fabbing some arms from some water pipe and angle iron
and run thru the suspension travel and roll to get a trial and error initial
wishbone length and location, then use the data to make up the 'real'
wishbones.
Argh, argh, AAAARGHHH
