Heater blower motor
 

I am rebuilding the heater and A/C boxes from my W108 280 SEL 4.5
Had the heater core re-cored and have it all cleaned up and ready to be re assembled. I would like to replace the heater blower motor with a new one
but cant seem to locate one, or one of similar size. I rebuilt the A/C blower motor and it operates fine. has any one located a suitable replacement. I tried the original Bosch part number and the one off EPC to no avail. would appreciate any info on a replacement.
The A/C evaporator looks pretty good but expect that after nearly 50 years and a conversion to 134a it too might leak. Could use a lead as to where to find a replacement for it also.

Finally located a heater blower motor. Ordered it from Germany.
It is a brand new motor just for the W108, ill just have to pull
the squirrel cage off the old motor and install it on the new shaft.
price was tolerable, shipping not.
Thanks for all the suggestions.
