Hey Vitamin c, if you're serious the Cucamonga Service Station is still standing near the intersection of Archibald and Foothill in Rancho Cucamonga (SoCal).
The "Cucamonga Garage" building behind the service station suffered a roof collapse and was just torn down in 2012.
Inland Mopars Car Club meets not far from there. Our next club meeting is next Sunday morning (01/06/13); I'll try and get some current pics and post them here.
