77 cj5 disc brake swap

Hello. I thought I had my dana 30 disc brake swap all figured out. I needed was new hubs, rotors, calipers, caliper brackets and bearings. I have recently read on the net that I need the knuckles from a disc brake front end. Is this true? Could some one let me know before i rip her apart

Thanks
Jonny

In 77, disk was an option. My 77 had the 4-wheel drum plague too! The 6-bolt spindles will mount right over.

By the way, this is a noob question!.

AAH! I now see you are a real noob, as in numero uno! You need to go to the newby forum and read the rules to understand!

My question was not a newbie question. Maybe new to Dana 30. It is perfectly reasonable that different knuckle may be needed to clearance the rotor or caliper when going from drum to disc.

I have been doing this stuff for a long time. Too long to be considered a newbie. I just really wanted an answer if anyone had done this.

For someone that answers my knuckle question with a spindle answer and then hint that I am a dumb ass and that I need some instructions is kinda funny. How can it be a newbie question when you can't answer it? I did read lots of posts in the "non-newby" area and there are some very stupid questions. Not that I am criticizing anyone.

I understand not wanting the "How much lift do I need?" and the "I have 1000 bucks to spend" questions. But judging someone by the number of posts is ignorant.

Thanks
Jonny

a. you got your answer without needing a Nomex suit. Be happy. Swapping stock stuff is a newbie question. Be happy.

You can go through the pissing and moaning of swapping knuckles, but it's not worth it. 5-10 min. with an angle grinder on each drum knuckle, the calipers will clear just fine, and the knuckles won't be any weaker than before.

EDIT: I should note, since you didn't mention which style of front brakes you were using, the above easy-peasy version will only work with the 77-79 6-bolt caliper bracket styles. Of course, since these are the only versions you should even bother swapping because they're stouter and use the better 6-bolt lockouts on the hubs as well, I took it as common knowledge.
