Question Parking Break Assembly

[WifeLovesToyota]

I just completed replacing rear breaks and rotors on rear. Drove two feet and heard clicking sound. Took of rotor and three pieces (small spring, twho flat metal peices) from the parking break assembly fell out. Anyone have an image of the assembly and know how to work in this very tight area? I have a Haynes repair manual, but it only gives the Tundra image, not Sequioa.

When I removed my rear rotors I hadnt backed the parking brake shoes off far enough and I popped these pieces also. If its what I think it is, there should also be a small retaining rod. That rod, in conjunction with the spring and round collar, hold each shoe to the backing plate (there might be 2 collars on each shoe, I dont remember).

There is room to work, but very, very little. I needed a combination of needle nose pliers (both straight, and curved tip), a flathead screwdriver, and LOTS of patience. A third hand would help. The first one took me about 1/2 hour, the second one took about 2 minutes. I do have a pdf of the manual at home, but not here. If no one else posts it today, I will do it tonight or tomorrow morning.
