ive been poking at what remains of the door posts on the 'tc' (answer - not a lot

)
the way the factory built that cars is that the inner wing is spot welded to the a post (the part that would have the light switch in), the inner boxing plate is then welded in last to the a post and the inner wing (and has no real reference point - if it touches, then it fits - it just stopes the a panel and a post from twisting round)
the a panel was part of the a post from the factory, so there was no 'jiggleing' to get the door gap - obviously with replacement parts the a panel is a seperate item, so with this in mind i think the better way than my previous method is as follows.
know roughly what the door gap is and tack the a post in place and check with the outer a panel and door, once your happy weld the a post to the inner wing and re check the door. then fit the inner boxing post and recheck the door gap.
once your happy with the door gap fit the outer a panel and try the door one last time.
once your happy fit the inner a panel - the inner a panel doesnt affect any fitment of anything else - so can be the last one to be welded - doing it this way allows the a post to be welded correctly to the inner wing and will stop the inner a panel rying to force the outer o bend outwards if you fit it all as a combo withthe door.
this method will only work if the scuttle is off as i dont think you will be able to juggle the inner around with it in place.
ive spent hours looking at the remains of the posts on the 'tc' car and the posts on the blue mk2 (which are unmolested and perfect)
ive taken some snaps as well
will this method work?
well, its how im going to do the a panels on the tc, so we shall see!!!
