Last week was another one step forward two steps back on accomplishments.
The PS pumps I purchased with remote reservoir tubes were about 1/4" thicker depth than my mock up pump. Which made the belt 1 rib off. While all Saginaw II pump bodies may look the same, they are not....
According to all the internet, only diff in type II pumps was shaft dia and reservoir attachment type. Here to tell ya that the internet is wrong... The early model .662 dia shaft also has a taller main body that limits how far back the pulley can be mounted.
The GM pump I used for mockup and fit perfectly was off a 97 Saturn. Which is like finding an 07 Duramax with a manual transmission now days. So when I noticed the 87 Sunbird pump was a no go, it left me digging for other options. Best guess, something from a more common engine same year.. And winner is, 3.1L v6 Grand Prix pump with .750 shaft. You can see the slight diff in pics below. About one belt rib in height. In fact the 3.1 pump has enough clearance to push the pulley even one rib to far down as I did in pulley comparison between it and the Saturn pump on right below.
Now any suggestions on how to fix a return line tube or AN fitting would be helpful.
