Question
I have a few parts from specific autos, and would like to know how to find their value before I advertise them for sale.Where can I go to determine this info? e.g. 2 headlights from a 1940 Packard

Answer
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
