Ah, the nightmare that is bulkhead alignment.
Did you set then bulkhead up before you bolted the wings on? (But with the old door tops)
Because now the wings are bolted on you've little chance of moving it.
I did one for someone on here the other week, who had took a truck cab off and fitted a hard top.
Doors where touching top corners as yours are.
I ended up having to unbolt all the wings etc and move a couple of inch forward to give me some waggle room.
We took all the spacers out from the foot well and chassis bracket was as far forward as possible. Ratchet strapped it forward, tightened it all up. Let straps go and it sprung back :doh:
Now I knew it would, just did so more than I thought it would.
Door gaps while they didn't touch weren't great.
The other option was to take a washer out from the outrigger and have a bigger gap all along. But he didn't want that.
So the next plan was to try and lift the tub slightly at the front. (He'd had the tub off before)
So unbolted it all from where it bolts the the chassis at the front, stuck a block of wood and a jack under the front of it and jacked it up. I.e opening the gap at the top and closing the one at the bottom.
Now this didn't allow massive amounts of movement but it made them look reasonable again, and pretty straight all the way down.
Sounds like you may need more than that but maybe worth a go for the sake of 6 bolts.
Oh and it's cracking on now mate, looking good
