Outer Limits 4x4 Board

G'day just after some advice
I have a 89 gq 4.2td had a lot of rust cut out of the roof
Gutters and fibre glass filler put in about 5 years ago its startin to bubble up and rust again. Ive just bought a very nice 96 gq body. Ive got a good panel beater who can cut the roof off and replace or should I just swap complete bodies? Any suggestions appreciated

I'd be more inclined to body swap if you could be bothered. Never seen bare metal repairs stay rust free.

it's a big enough job, but if your 96 body is in good nick, i'd be swapping
