6-lug Conversion Rotors Question?
Does anyone have a 6-lug conversion rotor they could look at? I'm wondering if there is a "CASTING #" anywhere on these rotors. If anyone could help out it would be greatly appreciated.

Re: 6-lug Conversion Rotors Question?
I have a set of Early Classic 6 lug rotors at home in my shed. I'll look, but all I remember is the "minimum thickness" cast into them. ECE disguised them well if they are an OEM rotor. They came in unmarked boxes.

Re: 6-lug Conversion Rotors Question?
mine came just like Tx Firefighters --someone is casting them for some OEM somewhere in the world.

Re: 6-lug Conversion Rotors Question?
I ain't no help, either. They came in a box, and they went on the truck. 5-lug GM rotors are a direct replacement, if I ever decide to go with that pattern option.

Re: 6-lug Conversion Rotors Question?
I'm hoping to get a casting # directly off the rotor itself... I deal with 2 mojor brake suppliers. I was told all rotors and drums all have a number cast into them for the cast molding. With that #, the part can be interchanged to my suppliers #. Thanks guys for your quick response.
Tx; I'm eager to hear from you. Bryan

Re: 6-lug Conversion Rotors Question?
That is true for most OEM or aftermarket OEM parts. (Key being OEM) The 6 lug rotors for the disk brake conversions are for custom aplications and are usualy made by the company that manufactures the conversion spindles most of witch do not use casting numbers. WES www.ClassicHeartbeat.com

The casting number on the rotors is "6069"

Re: 6-lug Conversion Rotors Question?
You should try the 1990 2x4 3/4 ton light duty rotors, they are 6 lug and have the same measurements as the early disc setups. That's what I am running but with the 1990 spindle also...

Re: 6-lug Conversion Rotors Question?
FisrtGen,
I already tried them everything was correct except the alignment... the rotor surface centerline was too far outboard in relation to the caliper... I was kinda excited until it came to putting it on my truck.... My cost was like $35.00 or so each... Oh Well..

bummer. I'm running the 1990 spindle, caliper and rotors so it worked for me. I just wanted to have a 6 lug with off the shelf parts... Good luck with it.

Re: 6-lug Conversion Rotors Question?
FirstGen,
Well Damn... looks like the second try was the same results as the first. So, I'll be looking into the complete spindle thing like you did... I'm interested in evertything that you needed. Do you remember? Do you just use the 88-92 ball joints on the 71-86 control arms? Then use the 88-92 outer tie rod end? or something different? PM if you'd like... Any help would be greatly appreciated.

Re: 6-lug Conversion Rotors Question?

Re: 6-lug Conversion Rotors Question?
I used the 88-98 ball joints on the stock 1/2 ton 67-72 upper control arm and then had to use a 3/4 TON 67-72 lower a-arms to make up for the difference in the spindle. Then I used a different outer tie rod which I will have to look up the number for...

Re: 6-lug Conversion Rotors Question?
FirstGen, Can you post all the info here so the rest of us can benefit from this conversion. Did you stock or drop spindles? That sounds like it might be a lower cost conversion than going with a new conversion kit.

Sure can. I have already posted this entire conversion about 3 times. At one time it was saved in the FAQ pages but I don't know if they are there anymore. anyway, I have drop spindles and bags now but origionally I used stock height spindles.

Re: 6-lug Conversion Rotors Question?
I have a pair of spindles off of my sons' '96 GMC Sportside, left over after installing dropped spindles. If anyone wants them, just pay the shipping. The truck had less than 60K miles when these came off of it....in summer of '02.
There would be a packaging charge, too. But, no charge for the spindles to anyone who wants them.

Re: 6-lug Conversion Rotors Question?
You'll have to make sure that those spindles had the 1.25" rotors not the 1" rotors which most of them had. The 1.25" rotor style are off the early 88-91 3/4 ton light duty 2x4... there are other year and makes but I don't remember off hand.

Re: 6-lug Conversion Rotors Question?
ChevLoRay, I'll take those spindles off your hands, if the packing and shipping to 25271 isn't too much.

Re: 6-lug Conversion Rotors Question?
FirstGen, I too looked through every page of the FAQ section and could not find it. Oh well. I am not converting mine yet...still priming the body parts. I will get to disc brakes long after the paint is done.

Well I dug out the part numbers. This is what I bought for this swap: FROM O'REILLY AUTO PARTS: 2 MOOG ES2020RTL - inner stock 68 style tie rods 23.99 each 2 MOOG ES2836RL - outer conversion type tie rods 35.99 each 2 ADC K6293 - Stock 1990 lower ball joints 29.99 each 2 Stock upper 1990 upper ball joints I used the ones on the spindle I bought FROM AUTOZONE: 2 BRAKE ROTOR #043398 also 5572 or 572 at 59.99 each I also bought the wheel bearings but you can just look that up there. Basically, I bought a 1990 model truck from K-member for like a $100. I used the spindles, calipers, brake lines, bearings, upper and lower ball joints, and factory rotors. You will also need a pair of 3/4 ton LOWER a-arm off a 1968-1972 chevy truck (C20). The only special piece in the combo is the OUTER tie rod as I have listed above from MOOG. The inner one is a stock 1968 chevy truck tie rod. It's possible that I have the two tie rod part numbers backwards but I remember the one off tie rod being more expensive than the stock one. You will also now need the 14mm lug nuts for the front. I went ahead a re-drilled my rear axles to take the same studs since the factory studs look weak as hell. -Taylor
