Wanted - Muffler Joint Nuts- XS650 Standard, '74-'79

[lewmoto]

I need the joining nuts that thread onto the front of the muffler and forms a compression fit with the headpipe. The ID should be approximately 49mm. The earlier '70-'73 nuts won't work. I'm willing to pay $50 shipped for a nice pair. The photo is of the earlier one; the later one may look different.
