Couple questions for yall

[NavyDoc]

Hey everyone, been a bit since I posted my truck while I was deployed. So I had a few questions about my truck

1. Is this the original steering wheel? I haven't seen a Chevrolet Division one before
2. Is a '68 like mine with a 327 and TH400 rare at all? My mechanic(I know, I feel less manly just saying that) who did the rebuild on it said that its a rare motor and even offered to buy it from me because he said its a large journal that is number matching to the truck. I've tried researching it but mostly came up with Camaro pages.
