Either TLE you choose to use, at the epoch of TLE 175 D12 had already passed 102.765 and was moving at 3+ degrees per day westward at 256 kilometers above the Clarke Belt. If you apply either TLE to D12's current position, it is projected to be west of 104W and the predictions vary by less than 2% of a degree.There's something weird about 184, but since the timestamp of 184 is older than 175 by about a day, TLE 175 is the more correct one and places D12 at 102.96 which is very close to the 102.765 final destination.
If the repair plan for D10 is approved, there's likely to be lots of other activity going on in the slot.
