If you getting a spare make sure you have 2ea right front lug nuts to secure it in the carrier. I bought a used M35A2 for which the PO had obtained a spare. Then he got some hardware store nuts to secure it to the carrier. The threads matched but it required a smaller wrench to turn them. If you are planning to used the issue lug wrench for this make sure the correct nuts are there. At least I figured this out before I got stranded someplace with a flat because I couldn't get the nuts off the studs on the carrier. The issue wrenches come in various lengths so make sure yours is short enough to fit between the carrier and the underside of the body.
