Hi, probably the first of many questions. Got a 1997 90 defender pick up that’s rather battered and looking at getting a used tub rather than attempting to straighten it. Not worried about swapping over just theres a few around. The only difference I guess is fuel filler location. So will all 90 tubs fit? Or are there any other changes. Also has anyone extended the fuel filler from in front of wheel arch to rear? As there’s a decent one not to far from me but filler is in wrong place. Cheers
