These are getting harder and harder to find. I did a quick online search on KSL and the Yards in SLC & didn't turn up anything. Years ago I picked up a lot of Scout parts from either Dwight's Auto Wrecking in Siguard (435) 896-8031 or Country Auto Salvage in Aurora (435) 529-3211. They had about 10 scouts between both of them about 10 years ago. Good Luck.
Not sure where you are located but about a year and a half ago I spotted a Scout II behind the Navajo Taco place on 3300 S and 400 E in Salt Lake. Not sure if it's still there or who owns it but maybe worth looking into.
I saw a scout sitting in what I believe is the yard behind pick a part in Orem yesterday, it appears to be sitting with all the cars waiting to go into the yard. It's a ways off the road, but I'll see if I can manage to snap a pic for you.
