Help: brothers upper and lower rollers for fuser reliable sources

[printerguymn]

I'm looking for any reliable sources for the parts for fuser assy. to rebuild them instead of replacing them. many times the cost is prohibitive if replacing the assy is the only option. I see a few on ebay and others but don't know reliability of them and accuracy of parts. the parts listing doesn't give the individual part listings of the fuser, just the assy.

Thanks in advance.
