Thanks Tim, I have scoured the internet for info on Truckstell, and every permutation of it I could think of. I have found copies of exploded views, and the installation manual online. I did get nice clear exploded view copies, but all the other documentation looks like it was run off with a defective mimeograph machine LOL. The gentleman I purchased the OD from is into Facebook ( I am not ) Told me there is the equivalent of these forums dedicated to 1947 to 1954 Chevy trucks. I guess I will go there, and see if there is something the swap meet there.
