When I looked at it before I was guessing by looking at it that it was old enough to be a gasser which I was hoping for simplicity's sake but I think I saw an injection pump. Probably not a piece of cake to get running again eh?
It all depends on whether or not it was running when stored, how long it was stored, if it was stored "properly", and what has been done to it while it has been sitting (i.e. attempts to "fix" it, parts scavenged, etc.).
Take a bunch of pictures (engine bay, underneath, trans, xfer, all PTOs, front & back of all axles, and the inside of each wheel).
Look for missing parts.
Look for leaks.
Look for anything that has been "Jerry Rigged".
Look for rust thru areas.
This is the right place to get help.
You'll get free advice, suggestions, & opinions.
Some of this will be worth what you paid for it (free), & some of it will be invaluable & will save you both time & money.
I'm looking forward to seeing it!!
