WANTED: rear turbo for 1973 T337G

[fsnewton]

Does anyone have a lead on an overhauled or new rear turbo for a 1973 T337G part number 406610-0022? I’m having my exhaust rebuilt and just found out that it’s near impossible to find a serviceable housing for them. Mine is running fine but I don’t want to wait until it quits before I start looking for one.

Thanks,
Scott
