I have finally after 20 years of trying acquired a 1958 Harley Duo Glide frame with the original swing arm. My first question is did Harley nickel plate parts in 1958? My swing arm has numbers matching it to the frame the swing arm is also nickel plated. Second question did Harley use what looks like Bondo in 58? If someone could answer any questions or point me in the direction of someone that can would be Greatly Appreciated!!!! Thanks for any help! Happy New Year!!!!
