Machinery bone-yards? Need Millport parts

Does anyone know of machinery bone-yards that will strip and ship parts?
I'd like to get the whole upper housing for a Millport, with the
pulleys. I know this is horribly extravagent to a hobbyist, but I'm in
the middle of an 8 week job and the head is really starting to get
noisy. I'm certain it's just bearings, but would like to try to find the
housing with the drive pulleys, rebuild with fresh bearings, and swap
over in an hour or so. Also, does anyone know if the Mill port is a
close enough BP clone that I might substitute a BP drive?

Thanks,

Jon
