spider kits
If I recall 0746-115 or 0746-118 are the spider / button kit that will work, measure width of rollers when you find kit to make sure.
1639-029 rollers pins bushing, again check widths, these fit the firecats and I don't think roller width's have changed since then.
cat doesn't show these in their late model sled parts breakdown, but lots of shops use these if it has to be done.
