85 c10 new brake pads won't fit

[plaidpotato]

I'm a first time square body owner, I recently picked up a 85 c10 2wd that was airbagged by the previous owner. I've been working on rebuilding the front end, just freshening up all the bushings and balljoints, tie rods, etc. I've run into a couple of issues I'm hoping you guys can help me with.

First off, the truck has new looking front brake rotors on it and the previous owner had tried to put new pads on it but could not get the new inner pad to fit. I tried myself with a new set of pads and found the same problem, the pad is a perfect match but seems too thick to fit. The rotors on it are 1 1/4" wide so I tried to install the 1" rotors thinking this would solve the problem but now the diameter of the new inner bearing is too small to fit all the way back on the spindle and the bearing in the larger rotors is too large to fit in the new rotors. I think the truck has drop spindles on it but not sure how to tell for sure.

The other issue I'm having is I had to replace the lower control arm cross shafts that mount to the crossmember, the guide holes in the shafts are not linning up with the pins in the saddle brackets, I can get one side in but the other side seems to be off slightly, so i cant bolt the control arms in place.

Any help you guys can provide would be greatly appreciated.
