Ross, Look on the boom's and stick's. There is a welded plate or maybe just some Cat Part# stamped there followed by a change (- #). Get those ###'s and post them here and I will check the pin Dia's. I think you would be best to weld up and line bore your boom and stick if it's only a repair you are doing not different lengths you need.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site." - Jason N
