5 to 6 lug wheels

[kaycee]

Getting ready for the 5 lug conv. on the 63 ,I am debating on keeping the 6 lug and getting new rotors or going to 5 lug and then changing the rear axles or drilling them for 5. If I go to 5 lug then I need different wheels or keep my stock 6 lug wheels and buy the rotors. My ? is will my 6 lug steelies fit the 85 C-10 disc setup that I'm using for the conv.

If your wheels only have 3 nubs to hold on the hubcaps they won't clear the caliper. Later-model 6 lug steelies will fit over disc brakes - they should have four "nubs." I have a pair of them (15x6) on the front of my truck and I'm using the CPP 6-lug rotors.

OH cool mine are 4 nubs ,was thinking of these and just running baby moons .I had a guy give me 4 white steel wagon wheels today. Does anyone know what used 6 lug rotors interchange on the 5lug spindles?

GM never made stock 6 lug 2wd rotors. You'll need to pick up a set of aftermarket 6 lug rotors or have 5 lug rotors re-drilled to 6.

Are your spindles the 1 1/4" or the 1" spindles? That could determine your next choice of action.

Another easy way to tell the difference of the wheels is on the back side of the barrel. If it has somewhat of a cone shape to it, drum brake wheel. If it's flat most of the way from center to lip, it's disc

Rotors are 1 1/4",I was thinking there was a 3/4 ton 2wd that was 6 lug but there I go again thinking. I would rather not re-drill anything so ay just grab some rotors

My '93 2500 2wd has 6 lug 1 1/4 rotors. Well, had. I put on 5 lug rotors from a 1500.

[kaycee]

Sean What spindles are you using?

[Just call me Sean]

They are stock spindles. My 2500 is a light duty so it has the same spindles as the 1500. Same calipers and brakes too. I only had to change rotors.

The 93 stuff is different from any of the 73-87 stuff though

This.

The 88-98 Lt Duty trucks that were 6-lug used different spindles, calipers, & rotors w/slightly different spacing/dimensions vs. the more common 71-87 spindles used when doing disc brake updates on drum brake trucks. Aftermarket 6-lug rotors for the correct spindles you plan to use (for disc brakes) are the easiest/best way to go.

I was just saying that GM did make stock 6 lug 2wd rotors. Maybe not for the spindles he has, but they did make them.

This comment was in reference only to 71-87 rotors. Sorry for the confusion it might have brought

True.

But since they're not easily adaptable to common aftermarket disc brake swap spindles I felt it was worth mentioning the difference for those that weren't aware.
