Have 2 drop members Scott's hot rod and porterbuilt

[laid67c10]

Ok so I picked up a new project and it has a Scott's hot rod installed with a manual rack and wilwood brakes, and their a arms of course, but I have a porterbuilt dropmember and michigan metal arms as well that narrow the track with and move the wheel ahead 1" as well, I'm familiar with the porterbuilt and know it narrows the track width too, but I'm not all to familiar with Scott's, but looks to be a very nice piece, does it narrow track width and move it ahead as well? I don't know which one I want to use any suggestions and why one over the other? Will the spindles and rotors and brakes swap over to the michigan arms? I have drop spindles for 73-87 also for the Michigan metal arms. From what I was told the rear is a bag on bar from porterbuilt and the truck also has the porterbuilt body drop kit also, it doesn't quite seem to lay completely with the Scott's in the front still looks like it's a 1/2 or so from the front of the pinch, wonder if I put the porterbuilt in there if it would lay out all the way? I'll be running a 6.0 LS set up in this also and have the motor mounts for both pieces to do so......,
Hers the truck, I'm not using the body i should have a clean and rust free 67 big window fleet body that will replace this.
