I am looking at buying a line lock for the brakes BUT I am not sure if the brake lines will simply mount in the line lock or not.anyone know if TCI makes a line lock that is a simple bolt in for 84-92 3rd gens ????

ehh, usually something like that is a cut/flare-to-fit application. There are some places, like summit, that sells line lock install kits. Pretty much tubing with nuts flared on, but whatever. I might be wrong though, but from what Ive seen its all custom apps.

slp makes a line lock that comes with pre-made lines.

slp makes it for the 87 and up i think

what is the difference between earlier years and 87-up? i thought it was 84-up when they went to metric fittings

it does say that its for 87 and up but it works fine in my 86. i have no idea what the difference is between years. i dont see any difference bewteen my 86 and my 88
