some 84 troopcarrier questions

On the old 40 series (which an 84 is) the roof gutters will handle a roof rack, the roof is bolted to the sides which are bolted to the main body.
You will have to find a tyre carrier from a later model swb (pipe type with the larger hinges and the vertical brace between the top and bottom tubes), reinforce the rear guard where it bolts on and also the latch mount. I did it on two 40 series troopies.
Or alternatively have some one make you a chassis mounted swingout carrier.

My mate has a FJ45 Troopie with a full length roof rack and wheel carrier and he carts all sorts of stuff on his roofrack. If you do fit a roofrack make sure you fit one with a continuous bottom rail made from flat iron where it fits on to the roof gutter so as to spread the load weight.

the 78 and 75 series troopys are rated to carry 300kgs on the roof.....not that I'd want to put that much up there!!!!
