I don't know. This is some axle Porter picked up and wanted me to post this question for him. I guess he got an 8 lug too. I told him to pull one side off of each and see if the hubs are the same. I would think they are...
Doesn't really answer your question, but this says the 6 luggers were from the big military jeep trucks. Just pull a hub and see if it fits on the 6 lug. The 6 lug shaft is gonna suck though having only 23 splines.
