1962 c10 rear end

will a 1963 to 1972 12 bolt rear end fit on a 1962 c10? or are there length issues such as the tire hitting the fenders, are the other cars it can come from? fleetside, shortbed
another option would be to find a disc brake kit for this yea, which i can't, and new gears, preferably with posi or limited slip.

thanks for the help

 

Get a tape measure and go to the junk yard.

 

The frame on a 62 is wider than 63 they are not a bolt in but can be made to work.

 

I've had a few sets of tires under the rear of my 65. With the stepside bed, 15x7 wheels, 255/70/15 tires, the tires rub the bed box and inside the fender lip on one side--panhard bar induces movement. Same rear suspension, fleetside bed, 15 x 8.5 wheels, 275/60/15 tires (wider tire and wheel) close quarters but no rubbing.
Disc brakes? How about front disc brake hats from a 88 and newer 4wd Chevy pickup, measure the thickness, and pick out the brake caliper that matches. 75 or 86 Chevy truck caliper? Both use the D52 brake pad. No park brake. Buy some dirt car caliper brackets, hoses for the front of a '80 4wd Chevy pickup front.
If it's a Chevy full size pickup with six lug, same bolt pattern. Use some imigination, and a measuring tape. Good luck!

 

thanks for all of the info guys, i already have to front brakes solved, and i have found an adapter kit to mount any 3in diameter rear end to it, i was just wondering id 8 or 9in tires would rub in the back on a 62 fleetside with a 63-71 rear end (i know the frames are different), rear end length of a 63-71 would be perfect

p.s. thanks for the info patrick2965

 

I went thru this in the summer. It ****ED.
The only direct bolt-in is a '60-'62 rear end, from a Chevy or a GMC.

The GMCs came with a Dana 44, which is a better rear end. 30-spline axles, no C-clips, and those rears are still used today, so you can easily get rebuild kits, Trac Lock, Detroit Lockers, and any other version of a limited slip dif that is still available in vehicles such as Explorers and Jeeps. And they're typically pretty cheap--I got one on Ebay that was a take-out from a brand new Jeep that the owner was putting 4-series gears in.

1963 was the first year for the 12-bolt, and it has the panhard bar's mount in the same location, but the trailing arm mounts are in a different spot. Later trucks have a totally different trailing arm that attaches to the top of the pumpkin.

The other rear end is the drop-out center rear, standard in Chevy trucks. It has a heavy, stamped steel removable round rear cover. These were available with Posi, were rare. New internals are very, very scarce, if available at all, and expensive. The posi clutches to rebuild the dif are made of unobtainium. They've got C-clip axles, with a course spline count.

Some Chevy trucks were optioned with the Dana 44 rear, but they're rare. The Dana cover looks very similar to the Chevy truck 12 bolt, but with 2 fewer bolts.

Axle bearings and seals are readily available for both styles of rear (drop-out carrier and Dana), as are pinion seals. Pinion yokes are readily available for the Dana...don't know about the drop-out rear. You'd be surprised at how a rubber seal can wear a yoke after 40 years. Even with a new seal, a used yoke can leak like a sieve because of wear.

For me, the best thing about going with the Dana was the availability of brand new DANA-brand gears. Nothing like OE quality for gear sets! Nice and quiet. And if you don't want to go with the new Dana gears, there are aftermarket gears available in any ratio you'd want...you can really fine-tune the gear ratio.

Hope this helps.

If you've got a bit of money to spend, you can have Ultimate Driveline in Grand Rapids, MI build you a brand spankin' new Dana 44 for your truck. He did the one in mine after we found out the original was junk (spun bearings). Your stock drum brakes will bolt on, and the rest is brand new. He'll need your junk rear end to scavenge the brackets off of. You'd need new axles too.

awesome response brad54, but do they sell a disc brake kit for the dana 44 on the 60-62 gmc, because i know they sell one for the 12 bolt on the 63 and newer

 

the 63-69 rears are the same length as your 62, as far as I know. The 70 and newer rears are a bit wider, I think an inch and a half. The 71 and newer rears have 5 lugs (except 4x4s). 73 they went to leaf springs.

 

thanks everyone

 

I have 305 2brl in 62 stepside. Need to know if anyone makes the drop out differential in limited slip oround 308 or smaller or is this asking to much. I called alburn gear and thay don't. I would put another rear in [coil spring], but can't find one . Was reading this thread and thought somone could help. Everything is to far away, in north east Indiana Any help would be grate

 

there are new aftermarket 3.38 gears available, but no posi, and the gears are expensive.
