Jesse,
Toyota's in general, and especially the Land Cruiser line, are about the only vehicles that will hold up long term in Haiti. Toyota's last the longest, and parts are the easiest (not to be confused with easy) to get.
I haven't made a set yet for an L2850, but it is no problem. Kubota has over 250+ models on the books now, so I sometimes run across a model that I haven't made any stabilizers for. I have measurements for an L2050 and an L2250, but the safest way would be to get you to measure some things for me. If you chose to buy a set, I can direct you in what I will need.
Your tractor would take a large set, which runs $167.00 shipped. That includes both sets of stabilizers, all new hardware for installation, primed, painted, and shipped to you.
I know all about the different "funds", and biding your time to buy something. Just let me know if and when- the price will stand for the forseeable future, unless steel costs jump.
In Christ,
Mark
