84 Indy 500 Official Truck

Hello, I was wondering if anyone has any info or pictures of the 1984 Indy 500 Official Truck seen in this link:

Any info, such as possible options, engine, production numbers, interior color, etc. is appreciated, especially if there is a way to identify an original truck. Thank you!

Looks like a standard s-series with a body kit.
