I knew dodge did that . the thought was that the centrifugal force of the wheel spinning would keep the lugs tight..... but that was for the passenger side. could be someone put a different drum assy on your truck.

I have the same thing on a 77 dually.
There is a question as to just which rear I have. I am still working to answer that.
As to your rims, they are likely to be lug centric rims instead of hub centric. They probably have alternating bevels on the lug holes. You will need to match these.
I have only been able to find them in 16 in.

thanks for the reply, thats what i remember from the owner that
the rear was a dually rear at one time...
What do you mean by hub versus lug centric????
Also what would be the biggest tire you canmount on the
factory rims

Hub Centric means that the wheel is centered off of the hub itself. Typically you will have a straight two piece lug.
Lug Centric means that the wheel is centered using the lugs. These lugs will have the tapers that mate with the tapers on the wheel.
I currently have some 235/85-16Rs on the truck.
They stand about 31" tall and are E rated. I'm not sure how much larger you would eant to go. Now I am limited to the 6" wide dually rims with the alternating bevels. I am not sure if there are wide rims available for that bolt pattern.
I am currently researching the possibility of replacing the hub assemblies with a newer hub centric version.

69crewcab, One ton axles seem to have these. I would assume it is to handle heavier loads without shearing wheel studs. They are 9/16" wheel studs. Should take an 1 1/16" socket to fit it.
Can't tell you why the drivers side, rear wheel has left handed threads. I found this out on my 82 (which is a 1 ton badged as a 3/4 ton) when trying to remove the wheel for the first time.
My truck came factory with 16.5 rims. But we have installed aftermarket 16" wheels. Any aftermarket wheel should fit it. We went with a steel white spoke wheel so we could use the stock lug nuts, the price for 9/16" chrome lug nuts for a full set were just crazy. The aftermarket wheels have larger, axle hub holes than stock. I believe only Ford stock wheels will fit, (maybe Dodge, not Chevy, this would be on the Dana 60 and 70's anyway) as the hub holes are a little smaller on other brand trucks.

Yes, Dodge rear axle, heavy studs for heavy loads :-) Dodge rear wheels should fit as well as Ford. 16" wheels are generally not a problem on the rear. It is when they have to clear the front disk brake calipers you can have occasional problems.
To figure out what size tires will fit on a certain size rim go to the tire company web pages and look up the tires you are interested in. They will have the acceptable rim widths listed as well as revolutions per mile and other neat things.

My truck has the big 1 ton calipers on the front and big drums on the rear and the aftermarket 16" wheels fit with no clearance problems.
I'm running 16x8 white spokes with 285x75x16 tires. I think these are 32 or 33 inches tall.

Reading these post over this rearend has me stumped now! Most all The big Time 4x4 guys look for these type of rears, They usually Have studs backwards on each side. They say these where a rearend used in older 1ton Miliary Trucks and are heavier duty then the everyday 1ton rears?
