None that I'm aware of posted here, but you can use that rib recipe/technique with some modification of the times out of foil, in foil, and back out again. Spares being larger, will take more time overall. I wouldn't go too much longer, if any, on the in foil part though. Bearing in mind you must keep strict control on the cooker temp, I would think, at 215-225°, 4½ hours then 1½ in foil, and then the grilling off to set the glaze would probably work fine.
