Drum to disc brakes, what size rotor?

[Bearcamp]

Getting ready to go to the bone yard Friday to look for my goodies to change over to disc brakes. I'll need 6 lug rotors but when I order them what size will I be looking for?

[lil_sahara450r]

6x5.5 lug pattern, 1 1/4" rotors, with matching spindles. and whatever else you want to change over to

Wow, that takes care of that, now just to find them. Do you think local auto parts store will have?

No.
What spindle are you using?
You need a 71-87 HD spindle or aftermarket 63-70 disc conversion spindle.
All 6-lug aftermarket rotors are the 1-1/4" HD version.

I'm gonna run a 2 1/2 inch drop spindle. Probably someone that's well known cause I don't want junk. Going friday to get the a-arms, calipers, rotors (won't need them) and spindles (won't need them either) Is there anything else I should get cause it's only costing me 50 bucks for whatever I get. I plan on using my original crossmember. and would like to change over to power steering. Would I need the crossmember to do that or can I mount the steering box without too much trouble?

You will need an adapter for the power stearing.Captain fab sells them.Thats what i plan on doing when i do my power stearing.

[Bearcamp]

Well then I'll need a power brake adapter and a power steering bracket from captainfab. I've seen some of his work on here and it's very nice.

[lolife99]

Get the steering linkage.
Centerlink, inner and outer tie rods, ilder arm, etc,
I would find a 71-72 or 73-87 donor.
Just make sure the 73-87 donor has the 1-1/4" rotors.

What year is the truck you are working on?

[Bearcamp]

you got it. loading up the tool box tomorrow. And ya know something,,,,the wife is even going along to help. I think I'll keep her for a while.

[lil_sahara450r]

listen to whatever lolife99 says.. He knows these trucks well. and yes, captfab's brackets are the best out there and he is an amazing help to anyone on this board. as long as you keep reading old post (using the search function) and keep asking questions, you will be fine. Kudos on getting the wife to help, mine loves classics and it's one of "our" hobbies, its great doing something you enjoy together!

You can use your old control arms, but will need new ball joints for whatever year spindles you go with.

Chances are the donor ball joints will be junk anyways.

You can have 6 lug front rotors using OEM style parts, but most guys here prefer to go the above mentioned route.

Here is one of the threads about front disc brake upgrades. There are also many other helpful threads linked in the 60-66 FAQ Index located at the top of the 60-66 forum main page.

Am I looking to get the right stuff? I just don't want to get it all and have screwed up the first time.

Just make sure your donor truck has 1-1/4" 5-lug rotors,... so the aftermarket 6-lug rotors will work.
Some yards will just cut the frame behind the crossmember and give you everything.

[Bearcamp]

Thanks lolife, little bit of info that just might work. I can get everything for 50 bucks. But want to look for 88 or newer 6 lug wheels,,,,,right?

I would look for 71-87 4x4 wheels.
They fit better than the 88-98 wheels.

And that's just what i'll do. What's about the easiest way to tell the year of the truck? Other than knowing what they look like cause alot look alike from year to year,

My memory is going.
