Timing belt/rear wheel cylinder kits-? on parts needed

[partwerks]

Just to make sure my mechanic is giving me all the parts needed for the timing belt change, as I don't want to get into it and realize a part is missing.

He says I need:

1. Timing belt pulley kit w/1 or 2 pulleys??
2. One cam seal (leaking)
3. One crank pulley seal (leaking)

One rear wheel has a leaking brake seal & so I'll do both sides:

1. Two, rear wheel, complete cylinder kits w/shoes

I looked on www.germanautoparts.com but don't see the rear wheel cylinder kits spelled out?

Also, I've seen the wheel cylinders where some are 17MM and some are 19 MM, does anyone know what size mine would be??
