Wiper linkage questions 67-9 cuda

Forgot about this thread. Yesterday I noticed a couple of the felt washers could use replacing on my '67.
This linkage that goes with motor 2822 963 (2 speed, white switch plate, 2 speed switch)
has 2770194 and 5? stamped on it.

edit. According to the assembly drawings, those are the 1967 wiper pivot part numbers. Same for all A-bodies. Not the same as 68-9.
It also shows two "drive links and cranks":
2771968 2 speed
2771928 var speed

I'll try to remember to get a better pic of the motor arm and see if I can read any numbers.
