    I am assuming you are looking at rears?Any truck can be speced out in a variety of ways.If its a standard axle (nothing HD) Brakes are typically 4707 or 4709"s and drums would be a Gunite 3600A or equivelant.If you took a picture of the brakes so I could see the spring hardware I could tell you for sure

    47070R is what it says on the stick which is on the shoe. Would that mean i have 3600a drums?

    Yes that is a very standard set up.You can buy cheap drums around 70 bucks all the way up to top shelf centrifuse for about 170 bucks.If your drums have 3 or 4 'speed bump" looking ridges on top they are centrifuse style.They are lighter and last longer but more expensive.If they are on the truck and your studs are not long enough you may have to use that style.The part number for them is 89996B.The 3600A number is a cast drum and a gunite number ( a quality drum)but a parts house can cross to something cheaper if you want to use a brand like durabrake or KIC.

    I am making some generalizations without seeing your truck but I have done many 100"s of brake jobs and typically see the parts Im telling you about.I am assuming you have piloted wheels also??Although I havent seen any 07 trucks with budd wheels Im not saying they they cant exsist
