[First c10]

69 hafton,
Check out my builds for pictures but I did the same thing but with trucks that had closed knuckle drum axles. I changed them out. In Hulk Jr (see link in signature)I installed a 90 suburban gm 10 bolt front axles added a later model power steering gear box and adapter(from Captainfab). Installed a 8" dual diaphragm booster and master cylinder with a disk/drum proportioning valve off ebay(159$). The truck steers and stops better than my 2008... I was amazed on how well it drove.
FYI in the Hulk build(see link below) I installed the captain fab rear disk brake conversion kit. Other than the brackets the parts are all bought over the counter at any parts store (like Special-K said). Check him out he does great work!
Good luck on the build and post some pictures
oh and I bought SS brake lines for my truck (Hulk) with a 4" lift.
Hulk Jr stayed with stock length and rubber.
