I have a 1987 K5 with wimpy 10 bolt axles. gears are 3.08s. and I'm running 33" tires. [not good!] I want to swap in 3/4 ton GMs with 4.10 gears and have seen many posts and articles on how to install them. My question is; what about brakes?? I plan to use an 8 lug stock Dana 44 disc brake front and stock 14 bolt, drum rear. Do I have to change the master cylinder or power booster to complete the swap? Any info would be appreciated!!
