If it were my car, I would hold out for a close dated 704, since that is the correct one for your car. They are not rare, just may take a bit to find the date code that works.

Ok, so the 37 amp (1100704) should be what you need. I have a restored 1100700 55 amp that dates perfect for your car but need to check what I have for 704s.

Agree with Telly, you have a 69 rear case. The bolt hole on a 70 rear case is in the same location as the one on the right. Also, the one on the right looks to be clocked correctly.

Take a large punch, or something similar, and give the piston some firm wacks inward. This will break it loose and the spring on the back side will help to push it back out. You want to get the...
