So I've recently purchased a 72 Bonneville motor for a bobber project I've been workin on and found a pretty good deal on a 69 T120R frame. Will it fit? I've searched all over the web and havent found much engine related. Most changes from 70 to 71 were frame, breaks, seat, related. But what about the motor, aside from the rocker box covers and exhaust outlets that is. The motor should bolt up right? Were the mounts on the head changed too? And would you run into any problems converting the motor back to a regular oil tank? I'm sure somebody here has done this very swap before so thanks in advance for any help or suggestions.
