hi guys, trying to track down a couple of new rear hub nuts for the westfield, as you can see from the pic, I need the ones that you can notch into the end of the driveshaft

hello all,

its a 1991 with IRS. it has a sierra xr4 diff in, not sure on the driveshaft's though...

it now has a tuned 4.3 v8 under the bonnet :+)
