This oem, chrome(and heavily dented) rigid frame tank was modified to fit in a swingarm frame. I'll use it, as H-D intended,(in my early '54 wishbone frame). I cut off the cobbled mount, blasted off the chrome - and had lots of help from skilled craftsman . . . welding and fabricating the correct mounts. It leaked oil, and had JB Weld all over, trying to seal the leaks.. It didn't work. I've got many hours in this thing . . . and it still has a few dents. Adds character. Ready for paint.
