My 72 Blazer w/8inch lift 38.5x14.50 Swampers

I finally got pictures of my Blazer to post. This is the start to my resto project. Had to get the thing up off the ground first, always the most important thing to start with, lift and tires. Next was pulling the heater box , controls and heater core out to clean it up and fix the broken controls. I bought a truck cab just for the doors since my top hinges pulled out of mine and cut them to fit the blazer. Glad it had good heater controls cause mine were broke. Got the heater all put back together now and works great. Next thing to do is to replace the break lines, but I cant get the old ones off, can anyone help me on this. Looks like there is a big not on the back side of the frame where the brake line goes through. I cant get it to come apart. It is a pretty solid blazer but does have plenty of rust to fix.
