To my knoledge the gear was never offered seperatly. Had to order a complete crank assy. The later engines had a two gear balancer in them and the gear was bolted to the crank with taper head internal hex capscrews. A real good machine shop, with a lot of "know how" may be able to reweld it to the crank. If there is worn or chipped teeth, it might be posible to reposition it like some people do with starter ringears, BUT said machine shop will have to have the gear teeth precisely timed, before rewelding, and then rebalance the crank after welding, and then there is always the lingering the issue of worn teeth, and heat stress. As you saw, when you posted about needing a rod, there is a lot more variables than one would think in a 336 Case engine. You can eliminate the 3 gear balancer, and mount an oil pump out of a 6cyl engine on a proper sized 6cyl front main bearing cap, (big journal/little journal) but again this is a machineshop operation, and requires proper shimes to space the pump drive gear from the crank drive gear and an oil feed line from the new pump to the block where the balancer pump fed the block.
