Will NAPA have rebuild kits for the hydrovac and the wheel cylinders, or just rebuild services?
You can get wheel cylinders and master cylinder pretty easily. The booster you're going to have to put in the mail or buy a rebuild kit off the internet.
There is a bunch of factory documentation for changing tires on factory wheels. Logging chain wrapped around it is a good safety precaution. Initial inflation is the more dangerous part. There is only certain advice regarding those wheels allowed here - but I was able to confidently put new tires on my truck.
