Hi Chris,
Here is a page from the 1959 Resto pack on Keith Hardy's fantastic site. If you haven't checked it out already many hours of fine reading here.
http://chevy.oldcarmanualproject.com/chevyresto/59tld02.htm Sounds like the truck you are looking at (I almost typed "your truck") is a model 3634.
If you buy the truck I hope the purchase goes smooth as silk.
