This question is probably for Spanky, but I've noticed there are handles on the seat frame of some cabovers (see photo), while my cabover (1950) does not have the handle. I was wondering if these were introduced in '51 when they added the wing window. I have seen the handles on 2 wing window equipped cabovers, one was a GMC the other Chevy. I was wondering if my frame had been changed at some point or if these handles were added later. Anyone know?
What Tim said ! You'll also notice GMC COEs had the air cleaner under under the hood, attached to the cowl, and not under the cab as the Chevy COEs from 47-53 do. Chevy COE didn't move the air cleaner under the hood until 1954.
