Not as far as I know, but it is just a $100 housing from a Ford pickup, so who really knows. No tube-to-housing welds. I brought the pictures down to Bob Lambeck since I had to go by there anyway, and he said run it. The conflicting/angled patterns show that this set may be impossible to get "perfect", but it is well within the acceptable range as is. I'll still measure the housing as Bob George suggested.

Dan, the used Dana 4.10 OEM gear set I put in my Duster (same housing as yours probally, 3.125 axle tubes diameter) looked decent on the drive side  but I could not get a decent looking pattern on the coast side, I did have to have the gear set glass beaded to get the rust off of it before trying to set it up  I tried sevral different depths and ended up leaving it looking like your latest one It is quiet and faster than the 8 3/4 was  I agree with "Bucks up" Bob on running it the way it is now

Not telling you what to do,just some more advise. Take it to a reputable mechanic with experience and have him recheck everything.What do you have to lose after all the time you spent,and minimize your risk of ruining a good set of gears. He might find the problem and you will be more knowledgable for your next set.
 I wouldn't run it like that. that thing will knife edge the gears before long. I would send them back to strange if I were confident it wasn't something else before running them. send them the pics and see what they tell you.

Axle centerline is .046 above (away from the pinion) the mating surface of the caps.
3.125 - .046 = 3.079
I need to get the top of the pinion 3.079" below the cap face? I measure to the shiny machined face, right?

Just measured it... Currently I'm coming up with 3.107" from the bearing cap mating surface to the machined face of the pinion.
3.107 - 3.079 = .028 more shim needed.
If I add .028 more shim, I don't think there is any way I'll make it fit back together. That will put me at .071 beind the pinion. My first set of pics in this post (Attempt #17) was with it at .060, and everyone said pull out, less shim.
Something's not adding up.

If you don't know the correct pinion depth it can be calculted by measuring the thickness of the pinion head and subtracting it from the mounting distance for a Dana 60(3.125").The difference will be the depth that the pinion should be installed.If your pinion is marked +- a number,add or subtract it in thousands to your pinion depth.
Actually pinion depth for a Dana 60 is 5.000" minus pinion head thickness.

0.046 surface below centerline
3.107 surface to pinion face
1.844 pinion thickness
4.997
This is well within the stacked tolerances of my measuring methods.
Ths says I am very close. Whay would the pattern not come with it? The coast pattern has consistently stayed slanted throughout the range of adjustments I've made.

The gears did not have ANY paperwork with them... If you can fax them I would really appreciate it. Unfortunately, I only have a fax at my office which will open at 7am tomorrow. I'll PM you my number.
Thanks!

I used 3 methods with results within .001 of each other.
1) straightedge across the face with digital calipers measuring between the bottom of the bore and the edge
2) same straightedge across the bore, but used the depth probe on the bottom and subtracted the thickness of the edge
3) Inserted the race, and used the straightedge across the cover mounting surface and used feelers to measure the gap between the race and surface, then measured down from the edge to the mating surface, subtracted the gap between the race and the edge, and that told me how much of the cup was ABOVE the mating surface. subtract 1/2 of the race OD, and that gave me the C/L distance above the surface.
These are $300 Fowler certified/calibrated digital calipers, not some cheapie set.
My inaccuracy comes from measuring down to the pinion face. My straightedge won't quite span the case directly over the pinion. I can just barely catch the edge of the machined face, so I may be .001 or .002 off.

so the depth probe had a ball end? I was wondering if you may have used a flat end depth micrometer that wouldn't actually touch the bottom, giving you a low measurement, but that doesn't look like that's the case...especially since you hit it within .001" using different methods.

Check to make sure the cap is cut on the c/l.
DO NOT assume that it is cut perfectly when measuring to the top of the pinion. 
What does the cap have to do with it?
I'm measuring from the mating surface, not the cap. Are you suggesting the cap may be cut too deep and bottoming before securing the bearing, therefore allowing movement?

The bottom line is always the pattern. Even if you put it in with a tool it still gets tweaked by looking at the pattern. I don't know why your coast is looking like it does but i am not there. you have been all over with the pinion shim and this is the best you have gotten. If you are sure this is the best you can get and all the preloads are right run it.

Do you have a set of set up bearings? If not get some
