Super rare cap Jon! I've never seen one. But makes you realize how rare '62-'63 Custom 3/4 ton 4x4 GMC's were back when new and how super rare one is today in excellent condition. This is the only photo I could come up with from back in the day. It's small and grainy, not sure what is going on. I was under the impression the standard uncut hubcap would fit over the front 4x4 hub. IMO, the hole is much too small for the full axle, must be for the tip only. '71 photo for 4x4 hub reference. Bottom photo brand new '62 1/2 ton 4x4. Hub and hole appears much larger than the hole in your 3/4 ton cap.
