Regular cab, regular cab kit, and I changed it all out myself. Finished it up this afternoon. I've read that about the adjustable panhard and brackets being necessary to correct the rear end geometry, but I've also read several posts saying the kit isn't that bad and lots of people just installed it alone and were happy. I can't see how. The rear end does look to be farther forward than it is to the side, but it still looks ridiculous in that state. Also ordered a new set of upper control arms to get the front end closer to spec, with the intention of acquiring the brackets for the rear a little later.
I had a good idea what I was getting into regarding the issues caused by lowering, but I expected the height to at least be as advertised. Right now the rear end is already sitting on the bump stops, and is lower than the front by an inch and a half. I can't see the front dropping enough to correct that. Currently debating just cutting my losses, removing the belltech stuff, welding my front bumpstop cups back on, and putting it back to stock. Thanks for the suggestions and such though.
