I purchased a Jule frame for my BJ7 project and Martin delivered it to my house personally. I believe he probably was interested in picking up my other pieces and doing the complete job because he has had problems selling just a frame alone. After arriving at my home and Martin seeing my capabilities and jigs and fixtures fabricated, he gave me some pointers and critical dimensions to weld the three sections to the frame. I had wasted a year patching the old rusted frame and not being satisfied with the looks and strength. Replacing the original frame with the Jule frame is definitely the way to go. If you do not possess the skills or tools to build up the frame, Martin will provide that service also. One consideration is the Jule frame is approximately 60 pounds heavier than the original frame. This is due to using thick-wall tubing replacing the stamped 14ga original frame. Another note is the center rails are about an inch taller than stock. This provides additional strength. The frame is flat on top just like the original. The frames are made with the later BJ8 rear design and Martin recommends using the BJ8 rear springs and poly bushings. The rear spring mounting brackets are closer together on the front mounts than original. This eliminates the need for a panhard rod. The rear shock mounts are notched to fit the earlier models. Hope this helps you making your decision.
