GA WTB Eaton HO72 brake drums (8 lug one ton) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

66Submarine · 11-03-2013, 11:09 AM

I really need some 13" (x2-1/2") brake drums for an Eaton HO72; the full floating one ton rear. All my drums are shot. If someone has some they'd let me have for a reasonable price, it would really help me out.

Thanks

**yelmer** · 11-03-2013, 11:28 AM

they are hard to find . I had to look hard also. good luck too you

**LostMy65** · 11-03-2013, 11:39 AM

Have you thought about just upgrading the whole rearend to a 14-bolt?

66Submarine · 11-03-2013, 12:29 PM

No real reason to; it's already a 4.10:1 rear. If I had a 4.10 C&C 14 bolt laying around with heavier springs and good drums I might, but I don't as of right now. (Only a cab and chassis dually 14 bolt will work due to width)

I just need to find the guy that swapped a good Eaton for a 14 bolt and I'm set. A couple good drums and I'll be good for another 48 years.

**LostMy65** · 11-03-2013, 12:31 PM

Yeah, it stinks I scrapped all my Eaton.
I would of just sent them to you for the cost of shipping.

BLK65K10 · 11-03-2013, 07:01 PM

I have a couple eaton rears out of a 63 chevy and 65 gmc duallys up in the junkyard I can see about pulling the drums and check them out for you. I don't know what condition they are in. I wont be able to do that till next weekend though. Let me know if you want me to. Thanks Lyle

66Submarine · 11-04-2013, 11:49 AM

Thanks Lyle; what do you think you'd want for them if they're good? I know shipping's going to be kind of brutal; those things aren't all that light. A guy in WV said he might have some, but if he doesn't then you're first in line.

BLK65K10 · 11-05-2013, 12:07 AM

The parts are free if you pay for my time to disassemble and measure. Probably 1 to 2 hours at $20 per hour.

obijuan · 11-05-2013, 09:31 AM

You can swap 14 bolt brake assemblies onto the eaton. Use the eaton hubs amd 14 bolt drums and backing plates. Im betting you have the 9/16 studs because of the big drums.

66Submarine · 11-05-2013, 11:19 AM

Sounds good, Lyle; do I still have to pay if they are unusable?

obijuan; all the old trucks used 1/2"-20 studs, duallys included. (IIRC '71 was when you got 9/16" studs.) That's my backup plan, though.

Good information. Thanks.

BLK65K10 · 11-05-2013, 10:42 PM

I'll have to charge double if they are not useable!! LOL!! NO Charge.

66Submarine · 11-06-2013, 02:21 PM

Lol. Sounds great, thanks. BTW, I have another dually with totally shot drums on it, so if you want pull all of them off and check them out, go for it. I also could use the hub bearing adjusting nuts/washers. (Seems like the PO figured that some of them were superfluous, lol.)

al4627 · 11-29-2013, 10:06 PM

This may be too late for you but someone might need this. I watched online and when Autozone put their 20% off free shipping $100. Bought new drums for a total of about 80$, as I recall. They shipped those drums (probably 60# plus) Fedex 3 day. Probably cost as much to ship as I paid for the drums.

66Submarine · 11-30-2013, 12:56 AM

Welcome to the forum!

blk65k10 has a couple he's going to send me; this is a one ton truck, and I'm pretty sure the rear drums are not even made anymore.

al4627 · 11-30-2013, 03:03 PM

Mine is a 83 GMC C3500 1 ton dually (same 73-87 I think). However, you have the earlier vintage and I imagine you are right.
