It sounds like it could be a truck housing with the bigger tubes, if you had the ends cut off and they were standard bearing ends i guess it wouldn't be....but if you got the housing with the ends cut off already it may have had floater ends on it at one time. Either way it's no biggie.
Ignore the ring deal for now till you get the housing cut, what you need is a pinion center finder to measure the housing for axles.
To over simplify it....it's a plate that bolts to the back of the housing and has slots cut into it that allow you to hook a tape measure up and measure the tubes. The plate has multiple holes in it for different model rear axles..12 bolt, 9", 8 3/4, etc. when you bolt it over the cover opening on the case the slots will be exactly where the pinion gear centerline is....thats you take off point for all measurements.
You can get a center finder from a few places like chassis engineering, allstar performance...etc...or check ebay?
This is also how you will measure for your pinion offset on a Mopar since the chassis nonsymetrical.
As far as the bracket holes go, you can open them up to fit the tubes. keep them a tight fit..." tap to fit" for the best weldment.
I would do all 4 at once and keep them tightly bolted together, you need to keep all the 4 link holes equidistant from the chassis brackets.
Also have some large spacers made that are the exact same thickness as your rod ends, that way when you weld the 4 link brackets to the axle you can keep them parallel and the holes lined up. You would simply bolt these spacers between the brackets. If you need some i can spin you some off on the lathe....they have to be exact or the whole deal can end up like pooh pooh and have poor fit.
