May I suggest Casa Binieta (spelling ?)
Its Bonita, and I'd pass. It is very cool place for kids, but the food is kind of akin to a Swanson dinner these days. Althought they do serve alcohol now.
i know its a ways off but there is a wrecking yard in Ellicott that has only older cars...may wanna stop by. Webb and Company is the name of the yard. I lived in Colorado Springs for a long time, that is where I would go to do things.
This is hit and miss, and I wouldn't receommend it. They hold odd hours and are not always there. For the 2 hour drive it would be for him, surely isn't worth it to show up and they are locked down. They do have more old inventory than any other yard in the area, but the biggest selections of it is A body, and post 72 B bodies. The lone E body in their inventory consists of two partial front frame rails, a cowl, leaf springs and a few scattered nuts and bolts. They did have a triple white Charger R/T they were willing to sell whole for around $30k a few years back. There are a few yards with old stuff on I76 out of Denver though, but I'd imagine their stock would be similar. Any easy picking are long gone.
Hit craigslist to see any old iron for sale in the area. Rocky Mtn Performance Mopar is a local club that may or may not have anything goign on. Might also see if the local chapter of Walter P Chrysler has anything going on.
Temps vary considerably. Two days ago it was 76*. This weekend will be 60* with chances of rain. Bring a coat for sure.
