The front ones are infront on the core support just above the frame rails, then there is a bolt at the top of the fender close to the cowl, there will be one in the door jamb ( you can see where it goes to the fender inside the door jamb) and then one other at the botton of the fender, under the cab. You'll have to disconnect the light harness, and hood release, as well as the a/c lines( hopefully you dont have any freon in it) and the tranny lines, as well as anything connected to the inner fenders.
Almost forgot, keep track of the shins that come out around the cab area, you will want them put back for panel alignment
