There are lots of folks that could probably sell you replacement stock spider gears in a used form. I don't have any at the moment.
You can also install a GM 14 bolt detroit locker if you use the 30 spline shafts and have some machine work done on the carrier bearing journal bore in order to fit the larger shafts in place. Also the Yukon Grizzly locker is a similar option.
maybe you are the guy to ask I hope
what do you put in place of the spider gear assembly in the H072 today
it seems that there is nothing available
mine broke did some damage to the carrier any suggestions or who I should talk to
