1972 Steering wheel question

[Tbruz]

Greetings
Finally getting around to changing steering wheel from late model Chevy to a correct one from 1972.
Questions:
1) Is a Pick up steering wheel the same as the Blazer wheel?

The Blazer is Medium Olive Poly exterior, dash and steering column.
The seats, visors, rear upholstry and door upholstry is Dark Olive Poly.

2) What color should the wheel be Medium Olive or Dark Olive?
3) Does any one have any Pics of a stock steering wheel on a 72 Blazer?
Thanks,
Tbruz
