Re: Disc Brake Upgrade Reference Thread
i grabbed the whole front clip from an 85 c10 this weekend for my 64 and will start tearing down, cleaning, painting and stuff like that - couple questions
i plan on getting the DJM 3" drop spindles, can I use the drop coils i got from CPP that Im currently running in my 64 arms? there is a valve on the 85 that mounts ahead of the x-member - is that just a factory proportioning valve or is it the pressure differential switch? It has some electrical connector that I have no clue about - should i just replace with a basic prop valve or what? i dont have anything from my harness to connect to it the shim stack used on the upper arms is unreal - like 8 or 9 per side - any ideas why they would need to do so many? dude says oe spindles and stock coils?? |

Re: Disc Brake Upgrade Reference Thread
I don't see why you couldn't use your current front coils. Yes that is the factory proportioning valve. The wire on it is just for a low brake warning in case of a faliure in either the front or back system. You don't have to wire that in if you don't want. I would go ahead and use the prop valve unless it is leaking at the end or at the electrical connection.

Re: Disc Brake Upgrade Reference Thread
thanks for the feedback Capn as always!
this front end had an alignment problem it appears - the wheels are still on it - worn heavily to the inside - and the upper control arms have a BIG shim stack - the OP said stock everything, but the front end sat pretty low without a motor in it - so the front coils were cut - any way to verify this? Thats the onyl thing i can think of here to cause the wear Last edited by blackmopar; 03-16-2011 at 10:27 AM. |

Re: Disc Brake Upgrade Reference Thread
I am wanting to convert to 8 lug on my 64. what do I need to do? I have a 94 3500 (non dually)parts truck. can I use anything off of it? I plan to use the rear end and all, but I see some references here to front end parts from the newer trucks
thanks |

Re: Disc Brake Upgrade Reference Thread
The front suspension on the '88 and up trucks is completly different than the '63-'87 C10-30 trucks and the '88-'91 R10-30 trucks. The only possibility that I can think of is you might be able to use the '94 spindle, rotors, calipers, etc. if the upper and lower ball joints will fit the '66-87 C20 or C30 lower control arms. Is your '64 currently a C10 or a C20?

Re: Disc Brake Upgrade Reference Thread
it is a c10. would the upper and lower control arms from a 73-87 c20-30 swap to my mine?

Re: Disc Brake Upgrade Reference Thread
Yes they will bolt right up to your '64 suspension crossmember. I would recommend drilling out the U-bolt holes and using the larger diameter later model LCA U-bolts.
I'm just not sure if the '94 3500 lower ball joint will fit either the '73-'87 C20 or C30 lower control arm. I do know that the '88-'98 1500 and LD2500 lower ball joints will fit the '67-'87 C20 lower control arms. You'll probably have to do some parts comparisons to find out for sure. Of course if you can find a '73-'87 C20 front suspension for the right price, there is really no need to try and make the '94 parts fit. Unless you like the challenge.....

Re: Disc Brake Upgrade Reference Thread
Captainfab If I decide to run drop spindles from say cpp or any after market vendor. Question is what rotor and caliper will fit those A.M. spindles? Currently I am running factory power drum brakes all around.

Re: Disc Brake Upgrade Reference Thread
That is something that the spindle manufacturer should tell you. If I'm not mistaken, most spindle manufacturers design their spindles to run the '71-'87 1.250: thick truck rotors, and the D52 calipers. Of course there are exceptions, so you should find out what the spindle mfg recommends for a given spindle.

Thank you Captain! One vendor did not want to say instead he stated I must use their caliper. But think he is full of .....!

Re: Disc Brake Upgrade Reference Thread
Ok after debating over doing disc brake swap on my 65 C20, I jumped in and picked up a 3/4 ton 1982 crossmember assembly today. The first thing I came across on tear down is the rotors have larger than 1/2 inch studs (metric ?). I plan to replace rotors & calipers. Is there another year caliper/rotor combo that will fit these spindles and have 1/2 inch studs?

Re: Disc Brake Upgrade Reference Thread
Those have 9/16" lug studs.
That's the standard 73-87 lug stud size.

Re: Disc Brake Upgrade Reference Thread
I grabbed the upper and lower control arms as well as the spindles off a 91 suburban, it is the square body style (looks like 73-87) will these still work? or do i have to go back to the yard?
I drive a 66 gmc |

Re: Disc Brake Upgrade Reference Thread
Yes those parts will work just fine since they are the same as the '73-'87 components. Did you grab the steering linkage and steering box while you were there?

Re: Disc Brake Upgrade Reference Thread
Well, I'm confused...(again) I just ordered a front end kit with McGaughy 2" drop spindles, 1 1/4" rotors. It says I can use original tie rod ends and ball joints. Did I read correctly in the first post that this is not true?

Some aftermarket spindles are configured to be a direct swap & use the original drum brake parts. Other aftermarket spindles are configured for 73-87's which require the specific disc brake parts. All OE (junkyard) swaps using OE spindles require the newer steering stuff and/or adapting the tie-rods to the spindles. What parts you need depends on what spindles you purchased. If the mfr states you can use the original drum brake parts, then they're prob spindles designed specifically for that application.

Thanks Scoti, sometimes too much reading makes me overthink things. Has anyone used Captainfabs steering gear adapter with original tie rod ends and such?

Re: Disc Brake Upgrade Reference Thread
Well, one more time. Been looking at power brakes but I have a big block in the 63' and it doesnt look like I'd be able to get the valve covers off with power brakes. Anyone know?
