I was just going to do the fronts. Leave the back as drums for now. Until I see a really good reason for ditching the rear drums, they're going to stay. I'm not racing the truck and a lot of modern trucks still use drum rears (last I checked) and don't seem to have any problems, so why would my 71 be any different? That's my thought on it anyway.
I have the factory drums, but they are single piston and the Wilwood D52s are direct replacement with twin pistons for better pressure distribution on the pads. I've also upgraded all of my vehicles to a slotted rotor and figured I'd do the same for the truck. Since what I have still works, I'm debating on using my money for the A/C and other stuff instead of switching everything out until I need to or decide I want the upgraded brakes instead of the next item on my list. I'm still going to replace the booster either way, I just can't make up my mind on the rest of it.
