I went through this several months ago and ended up getting calipers from another car. The leak is probably the seal for the p-brake adjusting mechanism and the rebuild kits don't include that one. I had two parts suppliers get kits from different companies and neither had the seal. Rebuilt calipers seem to be hard to find although some outlets can get them for about $200 or so each. New calipers are $1200 or so and that is pretty hard to accept. I finally ended up putting BMW calipers on the rear and using a mechanical parking brake. I'd try to find some used ones if at all possible. Good luck.
