I have a +8 chrome round carrier swinger. The chrome is ok, but nothing to write home about. It looks like it was set up for a link but converted to no link. The conversion is ok, I've seen better and I've seen alot worse. It has a wheelbar mount on it also. I give $150 for it after being told it was a +6, but turned out to be an +8. I'd do $150 shipped OBO.
Below is a pic of the conversion. BTW I didn't do this wonderful job. If I was going to run this, I'd fix the bottom side.
