I didn't buy them, but my Buck came with Kubota lower arms previously provided by Valley Power. They're bent in sort of a z-shape. No problems unless my check chains are too loose, then they'll get over on the tires.
Looks good. Is that the orginal seat? Looks like it. OEM seats in good shape are difficult to come by and I can't find a source for new ones. Thanks for posting.
I put a generic seat on mine. It fits nicely w/o any modifications and is surprisingly comfortable. I'll check out the seats on TSC. It'd be nice to have an original style one for it.
