Using mustang rotors for 4.5" bc

Checked the IBI and didn't find the exact seal. Do you think a 1.687 ID will work? If so here are some to try:
1.687 x 2.506 x 1/4 National Seal 40154 or 442224 (Kelsey Hayes 54595)
1.687 x 2.506 x .312 National Seal 410154 or 6874S
1.687 x 2.506 x .375 National Seal 480363
