Yes a 69. Thanks for the information!

Captain
would those spindles work on 64-66 crossmembers?

Re: Disc Brake Upgrade Reference Thread
 

If you're referring to the '88-'98 2wd spindles, you will have to change the lower control arm to one from a C20. The '67-'72 C20 LCA's would be the easiest to make work. The '73-'87 C20 LCA's will work as well, but the bump stop bracket is taller. The LCA change is necessary to accomodate the larger '88-'98 lower balljoint.

thank you

Before you get too carried away, take a look in this thread:

Need to figure out what happened with this member's installation.

Re: Disc Brake Upgrade Reference Thread
 

Hey fellers, I've been trolling this disc brake conversion thread for a while as well as researching other drum to disc info. I've got one important question for me, and that is that I'd like to use either.....my original wheels-love my bow tie hubcaps, or barring being able to use them, does some vintage wheel maker make a wheel that uses 66 wheel hubcaps while still having the offset for most 6 lug aftermarket disc conversions?

Re: Disc Brake Upgrade Reference Thread
 

I am not 100% sure about this, but I do not believe that the stock original '66 wheels will clear the disc brake calipers and rotors.

BUT, there are a few places that make OEM style wheels that will clear the brakes and still use your stock caps.

Here is one source for the wheels:

Take a look at this thread;

Dino did convert to 5-lug on this truck, but used aftermarket wheels to keep the stock caps.


BTW, I have family down in the area of Texas. We have a family farm just a few miles east of Fredericksburg.

Re: Disc Brake Upgrade Reference Thread
 

Hey! Thanks for the vintage wheel link! Looks like I can pick up some black 15" OEM's there when I figure out which way I'm going on the disc conversion...
Yup, Hill Country is mighty nice, albeit not too great this time of year with the cedar pollen!

Re: Disc Brake Upgrade Reference Thread
 

Apologies for pulling a quote from a few years back but this caught my eye.

As I have a 66 3/4 ton, could I just grab some new ball joints and spindles for an 88+ 1/2 ton, and attach them to the a-arms I currently have. Then I could piece the rest of the stuff (calipers, rotors, etc) from new parts, since I planned on rebuilding stuff anyways.

Is this doable?

Re: Disc Brake Upgrade Reference Thread
 

I have not been able to confirm that this will work, but I think there is a high possibility it will. I just have not had the extra $$ to buy a '63-'66 C20 LBJ nor the time to tear apart my '66 C20 to check the size of the balljoints. I believe it was member Tincan1966 that said that the '88-'98 Balljoints will press into the '63-'66 LCA's. I just have not done it myself.

Re: Disc Brake Upgrade Reference Thread
 

did we ever confirm that the 88-98 6 lug spindles work? and do the tie rods need to be cut for normal ride stance? to get the front end alignment?

Re: Disc Brake Upgrade Reference Thread
 

You might want to look at this thread:
http://67-72chevytrucks.com/vboard/s...d.php?t=620262

This combo of 88-98 spindles resulted in too much positive camber that requires either moving out the mounting point of the lower a-arms,...
or narrowering the upper a-arms.
I don't think this member (or myself) finds much money savings in doing this swap.

Quote:
ok, I said i would report back when i knew if my fix worked, and it did.
However, I'm just simply going to say that if your considering using 88-98 spindles to do a disc brake swap, don't.
I safely made mine work only because I am so deeply invested in it with new a arms, ball joints, rotors, calipers, tie rod ends, and a ton of time that I felt compelled to make it work.

Re: Disc Brake Upgrade Reference Thread
 

I want disc brakes all the way around on my 70', which is "better"/ easier, 6 lug or 5 lug? I currently have 6 lug.

Re: Disc Brake Upgrade Reference Thread
 

The 6 lug discs are not any more difficult than 5 lug. The tried and true way for 6 lug is to purchase the aftermarket 6 lug rotors for the disc brake spindles. Which is better is up to you as far as what wheels you want to run.

Re: Disc Brake Upgrade Reference Thread
 

Thanks Captainfab, what about the rear? What stock caliper brackets, rotors, calipers, etc fit the 12 bolt rear end on the 70' ?

Re: Disc Brake Upgrade Reference Thread
 

There are not any OEM caliper brackets that will boltup to the 12 bolt. I make 5 different rear disc brake conversion brackets.

Re: Disc Brake Upgrade Reference Thread
 

OK, Iam confused, Why not just swap the cab , bed and nose over to a 87 donor truck or earlier model with all the front end and power steering and power brakes and disc brakes. I am a newbie at this but to me it seems easier and faster to just swap them over. Or maybe it is not that easy to do. Thanks Doc

Re: Disc Brake Upgrade Reference Thread
 

No it is not easier to install a '60-'66 cab onto a '73-'87 frame BTDT. It is one heck of a lot of work and due to the differences on the '73-'87 frame you end up with a 3" body lift. Then you have the possible legal problems with the frame and cab VIN's not matching.

A power disc brake and power steering upgrade can easily be done in a weekend.

Re: Disc Brake Upgrade Reference Thread
 

Thanks again, Captainfab! Do you sell your caliper brackets for the 12 bolt rears?

Re: Disc Brake Upgrade Reference Thread
 

Thanks for the info Capt. Doc.

Re: Disc Brake Upgrade Reference Thread
 

All of the rear disc brake brackets that I make are for the '64-'82 truck 12 bolts and the '80-'87 10 bolts. There are links to the for sale threads in my signature line \/ \/ \/

Re: Disc Brake Upgrade Reference Thread
 

1994 donor 2500 van will the a arms& spindles work on 65 1/2ton

Re: Disc Brake Upgrade Reference Thread
 

The a-arms are totally different and will not work. The spindles were previously thought to work, but a few members have had trouble with getting the correct camber degree. So until a solution is found, I would advise against using those spindles......unless you want to work out the issue.

Re: Disc Brake Upgrade Reference Thread
 

Nevermind.... This thread has changed since the last time I was on here my question was answered already.

Re: Disc Brake Upgrade Reference Thread
 

Well, I take that back. That did not exactly answer my question. What is the purpose of swapping the C20 LCAs onto my 64 for the 88-98 spindle swap? My spindles bolted right up yesterday, but I must be missing something somewhere?
