Welcome there Yo I built a chopper out of a 70 750 frame (chopped) with a 78F engine my eveyday rider and my BABY is my 73K/836/70 engine Ive had pieces of it for over 30 years met a buddy about 12 years ago and he had a 75 aneb frame one of a kind 750 chopper and I always wanted one and it was a blast building it its a one of a kind also. not as decked out as my buddys but realy fun to ride I made some struts for it but I live in Maine and these roads will beat the hell out of ya on a normal setup so I put some stock shocks on it. It is so cool to go to the garage and scratch my head and say witch one do I ride today. Hey have fun with it Craig in Maine
