ATF versus Pentosin Pumps and Racks (Engine Swap Issue)

[bob]

If you take the original 3 bolt PS bracket from the 4000, flip it upside 
down, cut off the protrusion, then the 4000q PS pump fits fine. Not sure 
if its ideal but its been working for me for a few years now. Isnt the 
3B PS pump servotronic? I dont remember...
