68 gmc truck brake upgrades

[jserrato714]

Hey forum what up...Its been a while since ive been here but it feels good to be home. I picked up a new project today. Its a 68 gmc short bed. It has a big v8 engine. Not sure what size.. It looks like it has a brake booster and a master cylinder but it has front and rear drum brakes. That is a first for me..I thought that the booster was for power brakes?Not sure if the previous owner before the guy that I picked it up from did this swap. Not sure if its stock either? What do I need to run disks up front? Ive done this swap before but never on a truck that had a booster in place...? please help drum brakes suck bad....If you need pics please let me know Thanks peeps
