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

As far as the booster you must be missing the bracket and linkage assembly that goes between the booster and firewall. The under dash pedal assemblies are all the same. You need to get a complete booster assembly off of a '68-'72 truck to make sure you have all of the correct parts to install it. Make sure it has the rod that goes from the booster linkage to the brake pedal. Here are a couple of threads that may help....

I can't help too much on the spindles questions because I always change the whole front cross member to the later one. Just easier for me.
Here is a thread on the spindle swap that may give you the info you need.
