bobtail trayback or pick-up and pos use a td5 shell

hi all,a couple off you may have seen my disco 200 tdi ...td5 ...bits off alsorts well .... thing,im in 2 minds at the moment,continue as i am or as soon as it gets abit warmer start a major re-build(on a shoe string budget) as ever,so im hoping to get as much resurch done between now and then
.option 1 ,Ifancy picking up a disco 2 shell choping it behind the front doors and droping it on my running gear and building a tray back from there has any one ever done this ???? option 2 just go with what ive got wip the back of and make the tray back or pick up,does any one no witch is the easyest to build???? option 3 just leave it alone

i was a sheety for 5 yrs until the lure off a job as a trainy mechanic proved to much,so the metal work shouldnt be too much off a chalange providing i can beg and borrow the egipment i need and have a word with my old boss to c if he will let me use the gilly and press break ,

any tips or hints would be welcome ,especialy from some one who has done this before so i know what the hell id be letting my self in for ta shaun

p.s what thickness steel is used for the bulk head ,1mm tin or 3mm plate,

Decide what you want to do with it, then find out what spec u need to build to. I would of loved to drop a body on the chassis as I had to do allot of repair work too.. I used 1or 1.5 mm for the rear pannel with bracing. I forget.. but its not 3mm.
Cheers

ive always got a thing about going ott with what steel i use on the landy ,i geuss its the fear off the metal moth,im rearly fancying the pick up
