Power brake conversion

[BigBlockNBK]

Sorry if these questions are posted elsewhere. I am wanting to convert my 1970 C20 Panel from manual brakes to power brakes. I have the booster and new master already but looking at it the bolts for the pedal assembly that go thru the firewall are welded to the bracket, but the booster studs need to go thru the firewall in the opposite direction. So Im wondering if i should take it out and cut the bolts off or are there any other things that are different that are just gonna cause problems after I do that. Should I just get a pedal assembly off of a power brake vehicle? also the hole is in a different place for the rod that goes to the pedal so am I gonna run into something else when I cut the hole? Any thing else different about the manual brake and power brake trucks I should know about?

Another thing I want to do is drop the front 2 inches any pros/cons to doing it with drop springs or drop spindles?

I also plan on converting the front to disc brakes, I read on another site u can use '73-87 spindles and parts if u change the ball joints and tie rod ends. Has anyone done this? I have also seen where you can move spindles from one side to the other and flip it upside down to get the drop. yes/no? pros/cons?

Im sure I will have more questions once this thread gets going. thanks
