'69 C-10 wheel brake cylinder replacement?

[jdarren]

I have replacement brake slave cylinders for all 4 wheels on my '69 C-10. I checked my reproduction factory service manual and my Haynes manual for the topic but found nothing in either. So I'm gonna chip away at the built-up dirt and grease on the wheel and hoping for obvious bolt heads for the cylinder.

Aside from draining and refilling/bleeding brake fluid and reinstalling brake shoes and drums, does anyone have any advice or tips for removing and reinstalling the cylinder itself? Is it simple?
