Since you never received any formal "welcome" in almost 2 years, welcome to the site. I'm not sure where you are located but guessing somewhere in the central time zone. (may make a difference where you live on what help to offer since these are awkward to ship)
Last several years and until I eventually bought a pair for my 67, I saw many 65-66 ones available time-to-time on eBay (not always as a pair). Since I was looking for 67-68, I didn't pay them much mind. My takeaway on this is just keep looking on the Fee-Bay and you should find a set. Another option is to attend a local "Ford-Only" swapmeet. I know there is one coming up in Columbus Ohio Thanksgiving weekend, it happens Thanksgiving weekend every year for about +30 years now. Another in the Spring in Columbus and next June in Carlisle Pa. There are usually regional ones elsewhere in the country too (though I am not familiar with most of those, there used to be one in Pomona Ca.)
