There is a light blue 71 D-100 shortbed that has shown up on eBay a couple times now in Lenexa, KS. It looks real nice in the pics, and I decided to check it out the other day.
I don't want to bad mouth it or the seller publicly, but if anyone is looking at this truck I have seen it first person and would share my observations so someone doesn't buy something that isn't what it looks.
