Why do you need to run a TA05 pulley on the front? If it's to get rid of the overdrive, your best bet is to put what was the front diff (with the black pulley) in the back, and re-gear it slightly on the spur and pinion, probably up 1 or 2 teeth. You're better not mucking around with the 1 way if the bearings are pressed or bonded in, you'll likely break them trying to get them out.
