I have a Pacer truck topper that came off my 1940 Plymouth truck. I believe it was made in the early 60's to early 70's (Mfd. by Robert L. Erekson Trust, Billings Mont.). It fits a short bed truck with a box size of aprox 78" long by 48" wide. I had this on my 1940 truck, but no longer use it. This is very solid construction of wood with metal sheathing. It has been garage kept and show no signs of water damage or deterioration. http://cedarrapids.craigslist.org/pts/4616143078.html The Topper is located in Cedar Rapids, IA
