70 disc hub to 73 spindle grease seal

Hi,

I'm doing a disc conversion for my 70 Challenger. Wanting to keep the 14" rallye wheels so have got my hands on a pair of the 10" discs. The place that I got them only had 73 spindles. Easy enough to get the bearings to suit, but can anyone tell me what the grease seal is that works with this combination?

Just spent an hour with the local bearing supplier and the best they could come up with is getting a machinist to shave a 1/16th of the base of the spindle.

Thanks in advance!
