I once heard someone say it’s best to spend the money up front and getting a mostly complete halftrack, than it is to buy a cheap mostly stripped one.
Having gone down the second path when I got mine, I now agree that it is much cheaper to get a mostly complete one that runs, and you get to play with it sooner. They pop up on EBay Motors under “military vehicles” several times a year.
Good luck, look forward to seeing what you get.
