I found out the hard way that there are two different half-track rim, luckily I had spares to choose from so I was able to get a matching set, so I have a very nice rim for sale, with lock ring and bolts, this is the half-track rim with only two small opening instead of the standard 6. The lock ring on this rim has the riveted warning tag instead of having it stamped on. There is no major rust and rot, just surface rust. $125,Cost does not include shipping. It's the rim on the right in this picture.
