It's a DNA wideglide front end I bought from Liquid Choppers, they also sell NOS pieces for the CB750's. The rear disc I bought from the Wheel Shop in Pheonix Az when I went to the Grand Canyon this year, I don't know what it's off of, just know it'll fit an '84 to '96 Harley. I brought 50 pounds of chrome back in the airplane. They loved me at the security gate.... ahahahaha!
