Here's a few questions about my 1963 1500.

1. I'm trying to identify the model of power brake booster. My truck had a chassis-mounted camper on it so I don't know if the booster was factory part from GMC or if the camper manufacturer put it on. (I removed the camper because it was getting rotten...and I really wanted a pickup) Can anyone help identify this part, can you buy these still today, or have them rebuilt?? I haven't tried to see if the booster works because I'm going to replace the wheel cylinders and then flush the fluid first.

2. Do you have to remove the front wheel spindles to get access to the bolts holding the wheel cylinders on? Looks like the bolts are right behind park of the steering knuckle with no room for a wrench to get in there.

3. What is that canister mounted on the driver's side fender near the master cylinder? It has a vacuum line connected to the intake manifold and another line going to the oil filter mounting assembly. ?????
