Flamedabone, The best part of the H.A.M.B. is the great advice that one can receive on their builds and I really appreciate you bringing the idea to incorporate some sort of safety latch at the front door to my attention so they do not fly open at highway speeds. So I purchased the Suicide Door Lock kit pictured below from Heinzman Streetrods 402-886-2275 in Phillips, NE. and will install. I brushed on to protect the metal P.O.R. 15 on the inner side of the original '34 inner Passenger Door as pictured below.
