Was watching an episode of "Movin' On" last week on "RTV" and after reading this post I noticed a 64-66 GMC with bucket seats. It appeared to be a one ton or larger with a built-up camper on the back and as the occupants entered the cab area you could notice the bucket seats. They appeared to be as described in this article with a middle "filler" piece to span the driver and passenger seats. I noticed no padded dash or door panels. I assume this truck was stock as none of these were fluffed up until the late 60's. I also never knew these trucks came with these style seats as stock order. I have never seen these GMC years with factory bucket seats, only in later years. Thanks for the post.
