I picked up a springer front end this weekend at a swap meet. it's old, but it's in good shape. Heres the problem. I bought it to go on either my Higgins Colorflow, or a 58 Mens Columbia. When I got it home, I tried to install it, and found out it was for a frame with a 6" fork tube. The Columbia and Higgins have 5.375" fork tubes. I have an old ladies Hawthorne (pre war), and it has a 6" fork tube. What other men's frames will this front end fit. Sorry, I can't figure out how to post a pic here. Can send in an email.
