Found some what appear to be nice 24 volt two speed wiper motors. The picture shows a weather Pak water proof connector which is a plus. They are MIL surplus so hopefully good quality.

I am using weather Pak on my rigs now. Ten times better than the packard 56 unsealed vintage connectors for the civi market stuff I do.. Buying the correct crimper is key to success.
Obviously the OEM M truck military sealed connectors rock also.
But here is an interesting looking weather pak site.
