I would never criticize anyone's efforts to restore a classic car to its original condition. I did it once. I was very proud of it but found it frustrating to spend much more time keeping it in show(ish) condition than enjoying driving it. And, I couldn't drive the prizes.
I currently give priority to making my late-1966-built Pagoda as beautiful, as safe, as comfortable and with as much modern car functionality and convenience as is reasonable without being flashy.
I also installed a first aid kit. I do not remember where I bought it but it is only two or three years old and quite complete. The mounting system photos that I had seen in this site reminded me of something non-medical and non-automotive. So I designed a
five-sided box to fit the first aid kit, cut it out from some heavy cardboard, folded and glued it into a holder for the kit and upholstered it with left-over leather from my car interior. I attached it to the carpet with velcro on the bottom and a plastic push-pin fastener on the kick-panel side. I expect most people who don't own a Pagoda would not know that it's not "correct". After all, the car is 58 years old.
In the end, it goes well with my new-condition 1960's five-piece blue vinyl Pierre Cardin luggage set that is the same color as my upholstery.
