Further to the good advice given about the radiator cap, you would think that since every '32 standard commercial vehicle and big truck came with one they would not be the equivalent of hen's teeth. By the end of the '32 model run there more than 111,000 of those caps in circulation. Where they've all gone is anybody's guess, but I suspect most were simply lost or misplaced or left behind at gas stations. In any event, when you get your truck up and running carry along a reproduction passenger car cap and when you park your truck out in public and leave the one presently on your truck inside the locked cab wrapped in a rag. They have a habit of taking flight if left in place on unattended commercial vehicles and big trucks and to replace it requires lots of luck and serious money.
