I have a 55 300 also that's in really rough condition - I'll check the glove box in case someone at sometime put an extra in there- I have the one that was on the car but I'm still debating what to do with the car, it's one of the best 50s cars produced in my opinion. I think my best approach to getting this thing going again will be to find a donor 4 door to get some of my rusted out stainless pieces. Here are a few pics of my 55. Funny thing I need the hood emblem you would have one of those by chance?
