looking at a 1968 359 peterbilt, on the data plate says that it is a 359st what does the st designate
also has a what appears to be a later hood on it that is fiberglass would this year have a wide hood or a narrow hood
or could it have either, the truck has a 9spd road ranger trans and according to the owner a twin screw 2spd rear axles
that doesn't seem right to me
thanks for any help

It could have a twin screw two speeds, I have a set, they aren't common, or the front axle is the uncommon one to find, lots of single screw 2 spds.

The twin screw with 2 speed rears were usually set up with a 5 speed transmission and used as a 3 speed rear to make a 15 speed out of it. Low was both rears in low, intermediate was 1 rear in low and the other in high (hard on power dividers) and high was both rears in high..

All 359s had wide hoods. I looked for my Peterbilt book but could not find it. It is a great book.

Hi BGiese,

"ST" model has steel cab, frame rails, crossmembers & wheel hubs. Glass nose mid 70s & up. Does it still have the original cab or later 1100 style?

cab appears to be original, hood is fiberglass and looks to be a later model
