It has a bolt eye on top, and a stud on bottom. About 11". I've seen where I can buy a whole kit with new mounting points (at etrailer), but I wasn't sure if I'd get lucky enough to be able to find a direct replacement shock. Are there good sources that maybe I just haven't found yet? Or should I accept that I'll need a retrofit kit (or weld/modify my frame)?

I would start by removing one and getting dimension of it extended both directions and then go the someone like Monroe Shocks and find a listing of all their shocks by dimensions. Odds are good someone makes one that is very close. The configuration is a little odd but you never know.
I fool some with cars and when you lower a car you typically have to change the shocks because of the change in travel of the suspension. You get some dimension and mount stle and search for a replacement. I would do the same for a trailer.
Take the shock into you local auto parts store and they should be able to match it up. Let them measure it and select a match, if they don't know how go to a different store. they will want to know what kind of car it is off of, tell them it was an after market kit on a trailer so you you need it matched by size. Buy a standard duty shock not a Heavy duty.
I ended up ordering shocks for a Chrysler Cordoba (from summitracing.com), based on the mounting style and compressed/extended lengths.
The bolt eye had a rubber bushing, with a metal sleeve in that. The metal sleeve was too small of a diameter for the mounting post on the trailer frame. However the overall bolt eye shell looked to be the same size. Also the old shocks' bushing are in surprisingly good shape.
So using a torch, I heated the metal sleeve inside the bushing just enough to soften and loosen the rubber, and pulled the sleeve out. Then it wasn't too difficult to work the rest of the rubber out. Then I carefully removed the rubber bushing from the old shock, and worked it into the new shock. It fits great!
I would like to add shocks to my Shasta if you could do me a big favor and confirm the shocks you used and when you have time crawl under and measure the lenght between the mounting points( the plate to the center of the mounting stud), so I would know how far apart to place mine that would be a big help?
I believe that's the same one. But for your application I can't say if my measurements would work. The fully extended length should be easy to find, just jack up your frame with the fully built axle attached (wheels/tires/etc mounted). But the compressed length would depend on your axle-to-frame distance, the weight of your fully built trailer, and the geometry of your leaf spring. How long the spring is, how much travel it has, length of your shackle, probably something else.
For me it was easy because I had a shock to start with from the factory, I just had to match that. If yours didn't have one to start with, I'd consult with someone who knows a lot more about suspension.
Or, buy an adjustable bolt-on shock kit that can be changed as you trial-and-error your setup.
I can get that measurement for you, I'm just not sure how applicable it would be.
