Hi! Your hydro-vac will be under the passenger-side of the frame-rails.,toward the back of the cab. you've seen the "Service Detail",so you'll know it when you see it(Looks similar to boosters on fire-wall-mounted dual-reservoir M.C's.) Master-cylinder is located under "driver's'-side floorboard,with an access-cover,to add fluid/inspection. Hope this helps. Congrats on the truck-GOOD-LUCK,and please keep us posted! THANKS!!
