Good question. Wonder if a dealer will install an aftermarket part? I was thinking that you were wanting to approach it yourself, hence my earlier suggestion. I'm sure that there are a lot of unofficial mechanics out there that can do it, at this site as well. A place that sells the parts and does repairs would probably do it. Bailey's comes to mind, I think they sell big bore kits, but I'm not sure for which saws. Will they take saws in for repair via shipping and return them that way?
