hey shoota,
dont panic mate its good that you find it now rather then 2 years down the track once its coming through the paint.
take it slow just take heaps of photo's so you know where everything lines up when your welding it all in. spewing your not in syd mate my donor ute's got great iner door seal's you could weld straight in. make sure your outer door seal is not rusted out also, mine were screwed.
also a bit of advice i've been given and someone correct me if i'm wrong, i was told to brace the cab and chassi rails as much as possible to prevent it from twisting when cutting the floor/tunnel out.i was goin to put a few between the chassi rails and a couple in the cab half way up hinge/door seal. like i said dunno if this is 100% necessary but thats what i was told to do.
keep goin mate you'll be rite!
