Oil Pump Replacement

Well, Im sure Henry will chime here in a bit and tell me I told you so. So I got the new motor in and did about 5 passes Saturday. Well yesterday I went to pull it in the garage and the low oil alarm came on. Pulled the sensor, replaced with working on. Same thing so I took a oil test gauge and guess what noooo oil pressure. So I know this is the Oil Pump. And I know the nuts back off on these LLY pumps.
My question is what is the easiest way to tackle this job. I need steps. Mitchell is just to much for me. Im trying to get back on the road Saturday as I have another couple runs to do. The dealer near me had the newer LBZ pump plus nut and gear and gave it to me for $278 because it sat on the shelf for so long. I just, I think the fron diff comes out then the front tower and it will be easy, no? I know someone has tackeled this so I shaull see. Thanks guys
Drew

it would be easier to pull the motor out since you have to pull the front cover off as well as the upper oil pan.
