So I ordered two kits of 10 bolts, the longer wheel studs for my T170 rear axle hubs in order to safely attach the new 22.5" wheels I got. Ordered P/N 610-0159.10, and got these great big Dayton wheel Budd Nut bad boys instead.. They look to be about an inch and a quarter in diameter, and they're left handed.
I called the vendor and the lady on the other end was super helpful, they even had a line where I could text these pics to show them, so we'll see how it goes.
When I get the correct studs I will come back and put the pics here. Of course, then the easy part will be done and I might have to take the hub apart and install them.. I'm sure that'll entail some new wheel cylinders, and I'll then see how all that new hardware I installed in 1996 is holding up.
