Bob, These photos may be of interest to you. These,as best as I can determine, were used in the 42-46 trucks but may well have been a carryover from the late 30's to 42. Atool list from a GM publication shows you what was furnished by the Mfr. I have also attached a drawing of the hand crank (another bolter gave it to me). It looks as original as you can build. Good luck locating your jack and tools. Harold
