Where to buy cross pin retaining bolt -8.25 axle?

I was pulling my axles on the 8 1/4 and only half the cross pin retaining bolt came out. I was lucky and was able to turn the rest out with a small screwdriver. Anyone know where I can get a new one? Its a cone style suregrip if that matters.
Dorman 81848 looks like it fits a bunch of vehicles.
