ok guys i have come to decision that i want to cut out all my rust.... Ok so I'm looking for a t18 shell so i can cut parts of the rear end and weld these in were ive cut out the rust i can kind of weld enough to save my life but has no welder or second t18 and may need help from a fellow rollaclub meber here in perth id be happy to pay any one for there time cash or booz :) but how could i go abouts this could anyone help :)

Just as a note it's probably best to look for something other than a T18 to use for scrap metal considering 1) how hard to find they are 2) how rusted out they all are.

hmm but the sections that need replacing are above the tail lights and below

if you can...cut the section a wider then the rusted area so you have part of the shape of the metal, take it to a sheet metal fab joint and get them to make a new section up..
