Classic/Antique Car Repair: 1939 plymouth pickup, hemmings motor news, radiator shell

Question
Hi 2 questions,
(1) I need to update the rear end to something more user friendly my rearend is 54 and a half inches wide backing plate to backing plate what do you suggest i do or what will fit?
(2) where would a person find new name plate scripts for the plymouth radiator shell
thanks for any information; tony

Answer
What makes the 39 not user friendly? My stock answer for “where can I find….” Is to latch on to a copy of Hemmings Motor News, the old car hobbies classified bible. There are many companies that supply parts for old cars, trucks, and now RV’s and you will find them in Hemmings. www.hemmings.com
