FYI, I'm 95% sure the 42 Dodge rear bumpers components are the same for 46 - 48 Dodge. I know the front bumpers are totally different but I'm pretty sure the rears are the same. Good luck on the clock. They were manufactured by Borg in 1941. As you probably know, the US government purchased many cars directly from the civilian car production line, and put them into military use. They didn't need the clocks draining the battery so they took them out, if they had them. Some of these clocks have been sitting on military surplus shevles. Those individuals that have them, don't know what they go to. Keep looking. Ron
