I`ve been building scale model (1:24) trucks for a few years now and have never found a site that suited my needs. Only last week I had to go onto an Aussie real-life trucking site in order to discover what colour the engine block was on a Peterbilt, powered by a CAT. The guy who replied owned three of them and the help he gave was terrific.
I don`t know what standard you guys are at , so if it`s OK, I`ll enclose my latest offering. I`m going to monitor this site with a great deal of interest.
