69 Z/28 Day II Project (Air Force Brat)

To pile on, the C-clip eliminator kits tend to leak and do require irreversable changes to the tube interface. IMO if you aren't running slicks and sidestepping the clutch at 5k I would just buy a set of high quality replacement C-clip axles and call it good.

Yes Tony,

Have already looked at C-clip axles and they won't cut it with tech now days. Car should make near to 500 horse and anyone who knows me knows I enjoy side stepping the clutch at 4K. This car will see the track on occasion and in order to meet tech it's going to need c-clip eliminators or a conversion to 9" ends as it will be running slicks. Either that or if I want to step it up, a complete housing upgrade. (I can already hear the cheers)

I have considered a Moser 9" or maybe run a heavier Dana 60 and might go that route if I need a carrier and/or a new gear set. I'll know more on that next week and that may just be the option I choose so go easy here guys. I do not want a broken axle or torn up quarter panel just for the sake of saving an original set of axle tubes in a car that will never see the light of being a numbers car ever again.

Had a Dana 60 in this 69 I built up in the early 90's. With sure grip mono leaf springs, it was totally awesome! It saw 7200 rpm on a very regular basis and was my daily driver in the summer.

An aftermarket rear is never a bad idea but IMO you don’t need any of that at the power level you’re after. IIRC c clip eliminators are mandated only if you’re breaking into the 10s. Good luck with whatever you choose to do.

The S60 is a nice rear end with some nice upgrades over the original Dana 60 rear end. It's also usually a little cheaper than some of the other options. Moser also makes an upgraded 60 rear end.
I changed gears in my 9 inch last week and found that the bearing cap bolts on the ring gear side had stretched and bent, and I'm using the best nodular case that Ford made. The bolts are 1/2 inch, compared to the 7/16 bolts in the 12 bolt. My axles also have some twist in them. I'm going to have to upgrade to 35 spline axles and an after market case with larger bolts and steel caps if I keep racing this thing. I'm making 563 HP.

I've always been a fan of keeping true to the manufacturer where possible and with the technology today there are a few nice 12 bolt housing/C clip eliminator set ups on the market.

[big gear head]

If you wanted to stay with a 12 bolt the Moser 12 bolt has very thick bearing caps with 1/2 inch bolts and 1/4 inch thick seamless axle tubes with 9 inch Ford housing ends that have the Chevy brake bolt pattern. It's much stronger than the Chevy 12 bolt.

Probably not a bad idea Mike. Was going to rebuild it and beef it up, but building a new Moser diff is so much more in line with what this car actually needs. Planning on a 9K screamer for it in the future so I might as well build the diff I am going to need down the road.

I'll figure out what to do with this one later and might offer it up locally.

My brother Joe races NHRA A/S with a 396 L78/L89 G-Force combo and was the record holder (9.88 E.T. at 135+ mph) from 2016-2018 when NHRA reset it to minimum. He uses the Moser 12 bolt rear end, originally designed by Kenny Thomas Racing Enterprises (KTRE), with 5:13 Pro-gears and a 2:91 first gear ratio and the rear end holds up beautifully. I highly recommend this rear end. Don.
