Power brakes & Disc's up front, What all do I need?

[68GMC454]

i got a 68 gmc to..when i do it im going to do the whole cross meember swap..i already have power sterring on my truck,,would still rather do the swap..i figure i can get the whole crosmemebr and everything i need for it for less than 100..00 but i got a friend..so for me this is the route to go..but you might want to just buy the kit,,not sure what they cost...i will get the rear end from the same truck when i do this..so you might just want to buy a running cheap truck,,then you might have some extra parts to sell,,then take the rest of it to a recylcer that buy scrap metal by th puond..you might get lucky and have hardly any money in the whole swap..
