Scott, while reading the posts made after mine I realized I made a "typo" earlier, in that I first said the distance between my pin holes was 10-1/16". That was incorrect, and I've edited my previous post to reflect the actual measurement, which is
10-7/16" from pin center to center.
NIW suggested a SSQA...but I looked into that and was turned off by the cost of the set-up to convert from pin-on to SSQA. (It requires not only the adapter, but also to cut off the brackets of my bucket and weld on SSQA brackets. It came to thousands of dollars and that was ridiculous in my view.
I found a youtube video of a guy who makes a very simple QA that makes ordinary pin-on attachments into QA without a bunch of money or trouble.

The guy who made mine is Dan Heibert: danannah (at) gmail.com
ph: 20four-362-798four (Manitoba)
He made mine and shipped them and accepted paypal. (about $400 but mine were special one-off/custom-made due to special dimensions on my rare FEL.)
They are the cat's meow and didn't require me to modify anything. I leave the top pins in my attachments (bucket and pallet-forks mostly but ordinary pin-on attachments work without further expense or modification) and pick them up with the FEL and then install the lower pins ...and go to work! A few minutes to switch and no help required.
This is how they arrived, but Of course, I painted them
orange.
