The rear trunion on the mini draco and the regular ones are pretty much the same. I am pondering installing a left side charging handle sometime down the road so I decided not to go with a folder. If you are not concerned with the look of a traditional ak, you can put ANY stock from an AR on it or any of the ACE or triangle folders. here is a good video that shows stock options:

get the ace folder regardless as it's the easiest thing in the world to install. Like matt says, anything else requires some serious work. If you do like the fixed stock look, you can mount the ace folder to a fixed stock with a little work. A folding wood stock, though unorthodox, is easier than replacing and riveting in a new rear trunion. That's an older picture of mine above. I'm an ace fan. It locks up solid. I've hear people sometimes have issues with the push button folder, but the ace O.G. works really well. i'll see if i can find a picture of that folding wood stock thing...
I was thinking of going under folder for my next Draco, but that looks awesome!
essentially you just cut off the portion of the stock flush that goes into the rear trunion. You then take 2 wood screws and attach the ace folder to the flush cut area. I personally think it looks pretty good.
