sway bar bracket to frame mount?

[BUXMAN66]

the stock location for mounting a sway bar brackets to the frame, do you need to remove the factory rivet at the point that the core support is mounted to the frame?there are 2 mounting tabs on the sway bar mounting bracket that attaches to the frame and i'm wondering if the rear hole location,(rear hole, meaning the hole closest to your engine vs. the forward hole which is closer to your bumper) serves double duty in attaching the core support as well as mounting the rear hole of the sway bar bracket. i dont have a sway bar attached to my truck to use as a guide,but it seems i have seen this in the past.would it not be poss. if this is correct, to mount the sway bar bracket just forward of the core support factory rivet and mount it there?what would you be off...1/4 to 1/2 an inch ......i dont/t see that as being a major issue of geometry would it ?isnt the factory (which i got off of a '79 1/2t ) sway bar configured to a bend at the ends , which i believe would give you a little extra room to play w/?? thanks all .
