Sliding Gate Mis-Aligned After Repairs

If the track is angle iron, would it be possible to drill a few holes, maybe one each, run a tap, install bolts, raise as nec, ( think jacking bolt ) cut-off wheel excess above, and fill with loose cement, or not, - or just use bolts to remove angle iron, and re-bed . .
If you do 2 each side, once plumb, remove one bolt, install cement thru hole, re-install bolt, repeat with other bolt, viola, re-bedded
Or some variation .
Good luck .
