It looks like maybe the spindle studs are in the wrong orientation relative to that boss though. On mine, one of the studs is lined up with the boss.

Oh yeah, I was thinking it was on the other side.
It does look like the studs are clocked a little different.

The Ebay knuckle might be a 1969 or 1970 knuckle. That is the problem with converting the open knuckle 1969 and 1970 Blazers/Suburbans/trucks to disc brakes. The studs are clocked wrong to mount the caliper bracket.

Here is a purported 1969-70 NOS knuckle 360048



My 1972 donor knuckles had the single 1/4"-20 threaded hole to support the splash shield.
