Does anyone know where I can find or get Catapillar 22 rollers?

I am in Morgan Hill and have 15 rollers which are the same. -Wally

aren't the early CAT D2 like the 3J rollers the same all but the out side mounting i could be wrong but i slipped them off and slipped the 22 hardware on my 22 and they fit like a glove not sure if you are supposed to but i was doing two side x side in the shop and their they were and the more i looked the more they looked the same what did i have to loose nothing but BAM WORKED !!!!! well anyway in my case replaced all my 22 rollers with my D2 rollers i got lucky i do not know if this helps or i am just a goof but i though i would toss this out good luck
