The wiper motor and gauges are out. What a miserable job for an old guy.
First the wiper (vacuum) motor, it came out pretty easy, nothing got damaged and the motor still works. I carefully opened it up. Some grease was deposited in the lowest spot and the vane got stuck on it. I removed most of it and moved the vane by hand without problem. All got assembled again and I replaced the #6 special screw with slotted head screw from the local store.
Vacuum from my 53 truck got the sweetheart moving easy.
Some pictures below.
