[TR] Triumph Stag frame dimensions

[Glenn A. Merrell - TSN]

All,
Sorry to deluge all the Triumph lists.
A local repair shoppe has asked me for frame dimensions to put a Stag 
they have back to OE points.  Of course I directed them to the Stag ROM 
section 76, or to an unbent Stag or two that I have.
Problem is, the points in the Repair Operations Manual are all 
referenced to the Six (6) Churchill special frame jig tooling and points 
are all measured off of those jigs precision bolt holes or precision 
bracket edges for positioning.

I recall when I was a kid at the dealership in Pennsylvania that there 
were two US equipment companies - Great Bear, I think was one I remember 
that had all the frame points translated to frame checking straightening 
equipment buried into concrete from standard datum points that could be 
referenced from a set of squared up datum points on a flat floor / 
inlaid frame rails. 

Has anyone located any of these type of stand alone specifications, the 
full set of Churchill tooling, or other datum points and measurements 
that can be used to stretch a Stag back into proper "square"?   If so, 
please contact me.

Might also be handy to archive this information for all the other 
Triumph model lines, but I recall that TR7's and TR8's are programmed 
into some of the popular frame straightening equipment.
I know RATCO does TR4/5/250/6 frames and has those jigs, but Stags are a 
bit more rare in North America.

Thanks!
