The cab floor in my '50 3800 is more hole than floor. It hasn't had a tuneup in 12 years and is very much 'still under construction'. My mother in law wanted to hear it run because she used to have a '50 3/4 ton. So I got in and cranked it. It didn't start right up, so I let go of the key. (It's been converted to key start.) The keys immediately fell out of the ignition switch and through a hole in the floor, so I had to get out and get them. It started right up next try.

My mother in law said, "I never had to do that to get mine started."
