s10 rear into a 64

[csa daddy]

can i use a rear out of a s10 in my 64 c10. just wondering if i could or not cause i would like to use some 15x10 on the rear an want to tuck inside of wheel well

Member CVA59 put one under the '64 he used to have. That build thread should still be in the "Projects and Builds" section

It'll work width-wise, but just don't throw a bunch of horsepower at it or do any Funny Car burnouts. Those rears have small ring gears and weak internals. If you're just going to cruise it, it'll work, but just be easy on it.

What width are you looking for? Once you get that established, you can go find exactly what you need. There's some better choices out there, like a Camaro or Nova 10-bolt. Those things go for pretty cheap and can be found pretty easily. Much stronger than the S-10 rear, too.

how different is the bolt pattern for the gm car compared to the truck cause i got 5 lug truck rallys that have been stretch to 10's

Truck is 5x5
S10 and car is 5x4.75

I'm not sure on the width, but the Astro Vans run the 5x5 wheel bolt pattern. I believe they use the same 7.5/7.625 rear end as the S10's. And yes they are a weak rear end if you like to show how much power your engine has.

ive gotten old enough to know it dont pay to spin tires an act like a kid anymore so i may check into this rear may just stick with stock rear how wide of a wheel can i get on the back factory axle an keep them under the bedsides. cause i would really like a 10 inch wheel in back for some decent meats on the back

it's not just the width of the rim, it's also how that width is distributed, measured from the wheel mounting surface (WMS). For example, you can have an 8" rim with 2" backspacing (like I have) giving 6" of rim/tire out from the WMS or you could have a 10" rim with 5" of backspacing, giving you 1" MORE outboard clearance. of course the 5" backspacing yields 3" LESS clearance on the inside than the 8" wheel, in the above example.

It's all academic until you know where you're starting from. crawl under your truck and determine the inside/outside clearances you have now. pull one of your wheels and determine the backspacing/width. check the backspacing on your 10" wheels. do the numbers. This is a starting point and will give you a general idea how much you need compared to what you have, bearing in mind that different wheel/tire combos will have different overall widths.

How do you plan on putting the 5 lugs wheels on the 6 lug axles?

I have tight clearance with my setup even though the wheel opening flanges have been flattened, but I also have a '71/'72 axle, which is wider than the original '66 by 3/4" each side, which compounds the problem. I have run 10" rims with more backspacing (3.5" I think) but the tires rubbed.

[chevyrestoguy]

It used to be that most of the old style 10" wheels like the Cragars and Torque Thrusts had 3.75" backspaces and would always rub the outer fender lip if the truck was lowered. Years ago, I had a set of 15x10 truck rallys made and I had them put a 5" backspace on them and they cleared. It was tight, but the truck had a 5/7 drop with a 275/60-15 rear tire and everything cleared. Mine had a stock rear.

One problem that I found with a 15x10 with a 5" backspace is that it's not a standard off-the-shelf size. You have to have them built, either steel (inexpensive) or billet (way expensive). But, the fact that you're considering keeping the stock 6-lug rear, you'll have to either do an axle swap of buy a 6-lug rim. Keeping it 6-lug narrows your choices substantially. I would suggest doing an axle swap and going 5-lug. Or finding a 71/72 5-lug rear and bolting it in.

Your best bet is to get under the truck and start measuring. Measure everything, from the width of the wheelwells, outside fender lip to outside fender lip, inside of the wheel tub to the opposite inside wheel tub. Write it all down. If you've got a buddy with a rear wheel/tire combination that you like, borrow it for a few hours and put it up in the wheelwell and see if it'll fit. Is there a rear end currently in the truck right now? If it's not installed, then that's perfect because you've got room to measure.

There are so many ways to go on this, and each one presents it's own set of challenges. I would do all your measurements first, then lay out all the possible scenarios on a piece of paper with the pros/cons of each one. It'll help you decide how much time and money you want to spend.

I have an S10 rear in my 65, but then again I have an S10 everything in my 65

yes, exactly, I call that "frontspacing" and its a great way to figure out what wheels will "tuck" without rubbing.

please remember that the lips of the rim add 1/2" to each side of the wheel, so a 10 inch wide wheel will measure 11" lip to lip, an 8 inch wheel will measure 9", etc. this is important if you start with a string measurement to see what fits and then order wheels according to your calculations.

The width on the S10 (face of drum to face of drum) is 54.25". The one i did worth perfectly.

ok i have a 2 15 x10 truck rallys or 2 15x8 that have been stretched 2 inches on the front side of the rims. an i was going to have the original axles filled an redrilled to the 5.5 lug pattern an if i ever tear the gears out i will just have shafts made to fit. cause captinfab said that the newer 12 bolt gear setups can be used in the narrower axle housing. if the two wheels i have wont work what is the max offset on the front of a set of rims can i get away with. also my 64 is being bagged an i have the bed off right now.
i can measure how wide my wheel tub is but that doesnt tell me how much offset i can have between the front of wheel an the bedside

[csa daddy]

also it had 15x10 like ultra bullet hole wheels like a mickey thompson classic but they had way to much offset cause they set out from under the bedsides almost. the 31x10.50 would rub the fenders in the back but the bed that was on it was trashed an all out of wack. when i set the new bed on the truck the fenders rubbed all the way down

[CVA59]

I was running Cragar S/S 15x12 w/4-1/2" BS and M/T 29x15.5x15 tires, I was left with about an 1-1/2" clearance between the fender and the tire.

[Dinos63]

i used them in 3 trucks one in my 51 truck and in my 59 apache and also in my crewcab, i used a 2002 s10 blazer 2wd they have disc brakes and my crew cab i used the s10 2002 4x4 it was a posi , i had great luck with them

and crew cab

CVA59 that right there is exactly the kind of info i was looking for that helps alot

dino it dont look like the s10 rear is much narrower than the stock rear

thats a 4x4 rear, the 2wd is much narrower.

yup correcto!

[csa daddy]

i see so the 4x4 unit is the same as the factory rear in the 64 an a 2wd would be narrower

You betcha. Mine came out of a 1996 2WD Ext. Cab S10 if that helps.

[Warrens69GMC]

FWIW, you can get a 8.5 10-bolt in a 2wd s10 rear, no need to limit yourself to 7.5" rear end. If you have front disk brakes, you can use the camaro 1LE rotors (90-92) to change the bolt pattern to 4.75" for the front rotors.
