Funny how he all think it would be better somewhere else .  I actually had a 1970 Chev pickup from Charlotte . It was totally rust free . I thought it must be amazing to live in a place where things don't rot away from salt .

I see the poster that asked this question never came back . But I wanted to help shed a little more light on it for you . 

The first number 6 you got right . The 59 is the engine code . From my list from BMT , its a Cummins NHRS6B/320 . I honestly don't know what that is ,lol . Hopefully you can help in that department . 

You got everything else right , as far as I know . The ST at the end of the number means a little more than twin screw . The "S" means twin screw . The "T" means it was built to be a tractor . 

A guy named "Cam" on the ATHS forum says that the NHRS6B is a supercharged 743 cid engine, but supposedly they quit putting them in trucks in the '60s so maybe not the right engine code for this truck. If it's a '79 it should have an 855 Cummins.

I don't feel so bad now about the 59 in vin #. I knew the second/third number reference to engine ;; the 59 wasn't a common # I remember; 607// 685// etc. sure do enjoy the knowledge this forum shares.

Ya know it's another case of "live and learn" ;; all the new trucks i prep and worked on. never put 2&2  together with the ST vs S . a twin screw chassis usually long wheel base  was an S  signifying a straight truck  while the typical tractor (twin screw ) had the ST. 50 plus yrs later and the ole Polack is still learning. 😁

That makes this an interesting "U" model .  Too bad the poster never came back . 

Thanks for the info
