Terry,
in absolute honesty I have never measured,, especially like you Pro's!
The way I do the doors ( somewhere on the board (?) I have it all explained.
Wally you sound like one of the engineering guys!
And, I'm sure it works, But here goes again:
The doors are notorious for not lining up, I don't even bother anymore! I simply take the plasma cutter or a big cut-off wheel and cut the hinge plates right out of the cowl bar. I then bolt the hinges to the doors, one door at a time. Then bolt the "cut-out" cowl plate to the door. I then put the door in place, close the plate back up to re-fit in the cowl bar and hold the door in as perfect alignment as I can. (Two people work great but one can do it with shims! Then when I am happy the way the door fits on all 6 axis I tack in the cowl/hinge plate.... all looks good, weld the plate in fully.
Done. Now if you mounted the body as previously described every thing will go back together and fit as perfectly possible.
Takes longer to describe it than it does to do it! Like Cpteddie just showed, I put his door on in less then ten minutes just for a rough fit - and that looked good!
