I am still in search of the mounting brackets for a new idea 319 picker to an Oliver super 88. Pretty sure all oliver mounts are the same. Let me know if you have one of theese pickers mounted on an oliver. I would like to talk and see what it would take to fabricate a mounting bracket.
Pretty sure i have what you need. I have a complete 319 with a sheller unit in the barn with oliver subframe and mount. I actually had it on a Super 88.
