Re: Disc Brake Upgrade Reference Thread
The suspension from a '88 pickup will not bolt up to your '66. If you had gotten your parts from a '71-'87 pickup or '71-'92 Suburban, you could do as you are asking.
The complete pickup platform changed in '88, and is not interchangeable with earlier years. The only way you can use those parts on your '66 is to use your original upper control arm, a '63-'66 C20 lower control arm, and then install the '88 upper and lower balljoints, spindles, rotors, calipers, etc. This is the same as the 6 lug conversion described in this thread.

Re: Disc Brake Upgrade Reference Thread
This maybe a dumb question but; (Mine is a 68), Why not just put a whole front end under the truck, one with dics brakes. If I remember correctly, the 71 or 72 with 4 wheel drive front ends had a 6 lug patten too? Tell me if this can be done?
Thanks |

You can however remove the complete crossmember assembly with arms and spindles/brakes from a 71-87 1/2 ton 2wd truck to make it 5 lug with disc brakes. There are companies that make a 6 lug rotor to go on the factory spindle, that way you would keep 6 lug front.

Re: Disc Brake Upgrade Reference Thread
Here's a question. The previous owner of my truck put a 3/4 8 lug rear end on now my C10. I found a 80's 3/4 2WD suburban, a may sound silly, but can I put the front spindles on my truck so I can have matching rims? Does someone have a step by step on how to replace a rear end. either way I think i'm going to have to spend some cash. I just think it my be easier to do the front than the rear.

Re: Disc Brake Upgrade Reference Thread
If you want a 3/4 ton, then by all means go ahead and switch the front. But you will at a minimum have to change the lower control arm as well as the spindles, rotors, calipers, etc. IMO if you don't necessarily want a 3/4 ton, just change the rear end, it's a lot simpler. What year of truck do you have? If you want discs on the front, just get a 1/2 ton '71-'87 front suspension for the front. Then you could get away with just changing the balljoints, spindles, rotors, calipers, etc. Regardless whether you go to 3/4 ton or 1/2 ton front discs, you will need to upgrade the brake master to a dual reservior unit.

Re: Disc Brake Upgrade Reference Thread
Yes if you were to use a '73-'87 rear end you would have to weld on mounts for the trailing arms, and a mount for the panhard bar. I don't know off the top of my head what to set the pinion angle at. I would suggest checking the one you currently have and just duplicating that unless you plan on a big drop in your rear suspension. A '71-'72 rear end would be a direct bolt in but these can be hard to find.
It just kills me when I read about how much some of you guys in other parts of the country are having to pay for parts. Around here you could pick up a complete '73-'87 truck for $500 or less depending on condition and whether it's complete/ running or not. But it's that supply and demand thing...... Quote:

Re: Disc Brake Upgrade Reference Thread
thanks for the info. Ya'll are great. The 3/4 ton rear end is working so I'm not in a rush to change it. I'll keep looking. I found a nice kit for the rear end conversion kit.

Re: Disc Brake Upgrade Reference Thread
That is correct the '71-'87 C10's were not available from the factory with 6 lugs. If you want 6 lugs and disc brakes, you can either do the conversion with the '88-'98 OEM parts, or you can buy aftermarket 6 lug rotors for the '71-'87 spindles from suppliers such as CPP, ECE, etc.

Re: Disc Brake Upgrade Reference Thread
I agree with The Captain- I used 6 lug CPP rotors and calipers on 71 spindles and had no problems.

Re: Disc Brake Upgrade Reference Thread
I am looking at this post as a reference for a project I am working on to find some donor parts. The project is a 1963 SWB Stepside C10. I recently ran across a guy parting out a 1986 2wd Suburban and I think there are some parts on it I can use to convert to disc brakes up front as well as power steering. What can I use off of this vehicle?

Re: Disc Brake Upgrade Reference Thread
You can also use the rear differential so you have 5 lug in the rear as well as the front. However this will require some cutting and welding. If this Suburban happens to have an engine and transmission, that can be used also.

Re: Disc Brake Upgrade Reference Thread
I read somewhere that you can use the tranny crossmember from the suburban if you plan to do a 700R4 swap.

Re: Disc Brake Upgrade Reference Thread
Sorry to keep on beating this thing to death, but I'm still not clear on this one point. Let's say you already have 5 lug 1-1/4" discs (73-87 type). Will the 88-98 6 lug rotors work on the existing spindles, or do you still have to do the spindle swap? When I tried a parts lookup, it appears that the bearings are the same, A3 and A5, but is that enough to insure that the rotors will swap?

Re: Disc Brake Upgrade Reference Thread
88 - 98 rotors will NOT fit on the 73 - 87 spindles. You need to order 6 lug rotors from CCP or whom ever. It's the easist way to stick with 6 lugs.

Re: Disc Brake Upgrade Reference Thread
Yes the '88-'98 6 lug rotors do use the same bearings, and they do technically fit the '71-'87 spindles, but they don't line up with the calipers. So yes if you want to use those rotors, you will have to use the '88-'98 1500 or LD 2500 spindles and related parts. This also requires you to change the LCA to a C20 LCA.
Otherwise, if you're going to use the '71-'87 spindles, you will have to buy the aftermarket 6 lug rotors as Russ65C10 stated. Quote:

It doesn't have to be a '67-'87 LCA ? I have a rolling '63 C-20 Chassis that I am parting out.

Re: Disc Brake Upgrade Reference Thread
Russ and Captain, thank you for clearing that up. It makes sense that if a factory part would fit, there wouldn't be any need for the aftermarket 6 lug rotors.

Re: Disc Brake Upgrade Reference Thread
The '63-'70 C20 lower ball joints are the same part number. The '71-'87's are a different part number, but the ball joint hole in the LCA is the same size. The only issue with using a '63-'66 C20 LCA is the different shaft that they use. It is basically flat with holes for bolts to attack to the crossmember. So if you were to use the '63-'66 C20 LCA's on anything other than a '63-'66 C20 crossmember, the shafts would need to be changed to the '67-'86 C20 style.

Or, does it have to be '67-'86 in order to bolt to my 63' c10 X-Member ? I think I would prefer to use newer style rubber bushing style arms anyway...keeping it 6-lug
