Actually, I just noticed that the first motor and pump shown (A), seems to be the same pump as B, using the last cover shown. I think you can see the edge of the motor housing running through the rectangular hole.
You may want to contact Steve Hakel at restoration services.net as he restores wiper motors and might have units for sale. This is who I plan on using to restore mine in the very near future.
The top photo does have the wrong cover. It is also a "2nd Design" Washer Pump w/ a "1st design" wiper motor.
The second photo is a 1st design motor and pump.
The third photo is a 2nd design motor and pump. The 3 pins for the motor are now not hidden. But the pump cover is for a Pulse Delay system. Given the window and a third hole for the third washer pin.
Either one will work. Its just how "correct' do you want it. Mines the 2nd design.
