I'm not really sure what you're saying here. There are 3 bolts that hold the alternator to the bracket, and they're 13mm and found under the intake manifold nearest to the thermostat housing. You can see them fairly well from the right side if you shine a flashlight to the other end.I'm not seeing any threads in the bracket.
OK I see a SRT-4 motor... Your power steering pump is already removed judging by the picture. If you remove the intake manifold you'll see a bracket on the left-hand side and the rear part of the pump will slide into it and you will need the 3 13mm bolts to bolt it to the bracket.This is what i see if i look where you are talking about.
I'm trying to INSTALL it.
