I got a 73 duster with a 225 six the bearings are bad in my rear end i think it will be easyer just to change the rear end i live in long island new york is their any body close that has a good rear for a 73 6 cyl let me know
 
It would help if you stated what rearend you have in your car. It could be a 7.25 or 8.25 or 8.75 or Dana 60, etc... If you don't know which rearend you have, take a picture of it and post it up.
 
Most 73 225s had 7¼" rear ends. These units are as common as dirt. What is not common is finding one with Sure Grip. Mopar made them, but I haven't seen one personally. The 7¼ had smaller diameter axle tubes than the 8¼ and 8.75. If you decide to go with an axle with a larger diameter tube, be sure to grab the shock plates and clips (u-bolts), too.

Did your car come with disk brakes from the factory? If so, the wheel bolt circle pattern on the axle is 4½". Otherwise, with drum front brakes it had a 4" bolt circle pattern.

Any A-body is a potential donor. Rear gear ratios vary depending usually on engine and transmission. A very common 7¼" rear for 1973 225/904 combinations is 2.76:1. Other factory installed ratios used in 1973 were: 3.23:1, 3.55:1. The best way to check the axle gear ratio is to find a bronze tag attached to the rear cover. The tag will be stamped with the installed ratio. These things had a tendency to get lost, so you may not have one. The other place to check is on the build sheet (D51, D53, D56 respectively).

I've replaced a wheel bearing in a 7¼. I used a Dremel tool with a cut-off wheel rather than a cape chisel to get the old bearing off. Other than that it was straight forward and greasy. Good luck.
 
my build sheet says D51 mine duster is a plain jane drums all round with automatic
 
So what rear is in it, and where are you located. It's difficult to accommodate you without knowing those things.
 
I have a 7.25 that I will give you for free,, shipping would be $ from Indiana,,

keep looking,, folks give the 7.25's away for nothing or not much..
