Currently undertaking Rustoration (see thread for details. viewtopic.php?t=163051 )
Encountered a lack of rigidity leading to the cab door no longer closing, as it’s dropped a cm or more at the rear. This is in the context of removing the front arch, and rebuilding the B pillar.
I want it roughly in shape for rebuilding, so that the door closes when it’s finished, so am thinking about options for achieving that. And yes, I know prevention is better than cure, but we are where we are. I recall (too late) ?Plasticman I think? demonstrating a brace from base of A pillar to a third of the way up the B pillar before removing the arch, to avoid it spreading and hence the door dropping.
I’m in a limited space

and removing the door is not possible in situ.
Handy to have the door on for assessing when it’s in shape.
So any ideas? Options I’ve thought of are:
1. Ratchet strap pulling base of A pillar and a main chassis rail.
2. Jack under base of A pillar
3. Push (with Jack or something) on front of van at bumper level, bracing against end wall of garage.
I also have a length of threaded bar, that could be used…
So, ideas, experience, all welcome.
