Simple Gen3 swap question.

[Doubt_Incarnate]

i did some lookin, the gen 1 pump is slightly different, it isnt tapped for bolts, the bolts pass through the pump and thread into the mount behind it, i have pics, one shows thw pump where th bolt passes through (just 2 bolts i could see holding it) and the other is a pic of the remote resivior is relation to the pump.
