I have these two twin post mirrors. I think from a 65-66 Fury. The one with the dull shine is very tight. The other one is still useable but not nearly as tight but should still be fine unless you travel a lot of really bumpy roads. $20 ea plus shipping from Youngsville, NC. I have a video of them I can send ya that shows a better description.
