bobbys kit adds 4 more 5/16 dowles to the exsiting 2 and still uses the stock aliment dowls makeing it a 6 dowl pin hub. its the
ive never had any problems since the added dowls. you should have the shop put those dowls back in for you and then call bobby for the new dowls get them in and thank your self for doing it. very straight forward install and works awsome. just my .02
You can drill them out, thats how you mod your hubs to do bobby longs dowel mod
Also, usually the reason the hub studs break, is because they were loose. I check mine all the time now, becasue they do wear loose over time.
