The Lil Red Express was only produced in 1978 and 1979. Among other model year changes, the 1978s had the single round headlights and the 1979s had the quad rectangular headlights. Our truck was not at the Sonic that evening when those photos were taken (we went to dinner at another local restaurant). Here is a link to a slideshow of photos of our truck (photos taken by the seller from whom we purchased the truck) . . .

As soon as we took delivery of the truck I immediately had those "out the rear" exhausts removed and routed the exhaust back up through the vertical stacks the way it should be!
