The Indy single rider has been discontinued, much to my dismay. They haven't offered since last summer when they started making everyone watch the safety video.
Still available at DL is Splash Mountain, you enter through the exit.
In CA you have:
Soarin' Over California - get a pass at the entrance and enter via the Fastpass queue
California Screamin - get a pass at the entrance, but go in via the Wheelchair entrance, go to the elevator, ride up, cross the tracks and take the other elevator down.
Grizzly River Run - get a pass at the entrance, then enter via the exit
Mulhulland Madness - enter the single queue right next to the entrance
Maliboomer - enter the single queue to the left of the entrance
Tower of Tower - no specific single rider entry, but when you are in the boiler room, listen up because many times they will ask for single guests checking in and you can get on quicker
As for Fastpass, in CA, Grizzly River Run is not connected to the rest of the system, so you can hold a GRR pass as well as any other Fastpass, regardless of return time. This is also true of Roger Rabbit's Cartoon Spin in DL. Sometimes it works for Star Tours as well, but not all the time. Oh, and DL and CA are not connected to each other, so you can have a FP at DL and one at CA at the same time.
