The brake line routing is pretty on that one Mopardude but I prefer to run my brake lines on the body so I can just hang the calipers when I need to pull the rear. That way I never need to open the brake system to make chassis changes twocents

Got the old Dana 60 pulled out and the new S60 installed. Weather was nice so I took it out for a drive today. The new rear end is nice and quiet, the S-Trac seems to work just fine. It doesn't make any noise going around corners but tightens up when I jump on it. The 3.23 gears seem like a good match for my engine and transmission. I had to shift out of first fairly quickly with the 3.54 gears but the 3.23 lets me extend that just a bit more. The rear discs aren't bedded in yet so stopping power isn't up to par yet. That will just take a little bit of time to get the brakes dialed in.

Looks good Andy that 3.23 should work perfect with the super low gear in the 5-speed. Mine has a 3.27 low gear and I had 4.56 gears in the rear when I first installed it. I never did the math but I was shifting right after the tree. If Cass ends up making a run of the 3.23 gears I'm sure he will sell all of them.

4.56 with a 3.27 first gear is a 15:1 starting line ratio! That is the same as running a 5.60 rear gear with a standard 2.66 first gear.

The 3.23 rear gear seems to be a very good match for the Doug Nash 5 speed box. It is still a 10.56 starting line ratio which is the same as having a 3.97 rear gear with a 2.66 first gear. So it comes out of the hole just like a normal four speed car would with 4.0 gears, but then I have 3.23 gears when I shift into 5th out on the freeway. My rear tires are 28 inch diameter so it rolls pretty well down the freeway.

I hope you Devcon the plug weld holes from tubes to the housing. Mine developed an oil leak sitting in the crate. And figured it was a pinion oil seal. Nope, further investigation revealed all 8 plug welds had developed crater cracks from different cooling times from the differing materials. Tried re welding......unsuccessful. Filled them with Devcon, smoothed them over and never looked back. Another couple of guys over here have experienced the same thing with their S60 housings. Awesome product and great service though.

You aren't kidding the last 2 gear sets I done are the old factory deal. Not bad with a spool but that Powerlock is freakin heavy changing shims. I haven't had the opportunity to change gears on the new S60. I should trade my 68 housing in on a Strange S60 work Maybe with a set of 3.23 gears.

I've been driving the car whenever the weather is decent and the new 3.23 gears seem to work just fine. No noise that I can hear. The car goes down the road nice but still has move than enough juice to spin the tires at will.

I screwed the prop valve all the way in (max rear brake force) and that helped with the brakes but it still isn't perfect. I think I'll need to swap in a MC with a smaller bore size to get the line pressure up to work with the four wheel disc brakes.

Gday Andy,
I love your book on Wedge engines
I am building a 68' Dodge dart with all Mopar running gear this time, last time it was on the road it had a Furd 9"
With the persuasion of a local buddy he's convinced mem into building a Dana S60 with all the fruit.

I seem to be having contact pattern issues where there appears to be too much contact on the heel & toe of of the ring gear set

If i shim out the pinion bearing it becomes too deep

If u reduce it becomes too shallow (see pics).....
unlike all other gears i have set up this will not give me a perfect oval shape in the centre of the drive side.

From what i can tell the gear sets are not ground as well as a Dana Spicer.

Cass Esslicks "Dr Diff" 3.23 gear set and

Any input is greatly appreciated

The pinion is too far away. I would try a 0.005" thicker pinion depth shim and run another contact pattern.

I've been driving the car for four years now. No noise or any problems with the 3.23 gears.

Are they in production? I don't see them on Dr Diff's site.

The first production run of 3.23 Dana 60 gears is sold out, but I have 200 sets on order. They should be back in stock this spring.

Have you thought of changing the rear tires to a taller set like 6 or more inches in circumference (2 to 4 inches taller)? If not, maybe you look into that twocents
