I just used an analog divider to measure my frame. The frame is 7/8ths. The forks however, are a shade over 1 inch. The first time I put a picture of this frame on the forum, those in the know said they were not the original forks. Even though there is a bonanza emblem on the fork plate, no one remembered seeing a mid peg with the forward swept handlebars, or something like that. One person guessed Trail Head. So, I guess I wait until they get here, cut off the pressed axle holes at the welds, and see if they fit. I appreciate your help BEO. Anything else you think of that a 60 year-old retread (I'm not really a newbie-I had a Taco 22 when I was 13 or 14-or 46 years ago) might need to know, would certainly be most helpful.
