Duster rear end compatibility
3/4" per side is VERY easy to get to "drop on" RE: a 65-67 axle in a Duster.
VERY EASY.
Are there technical engineering concerns? Yes.
Does it work without modification? Yes.
Will you experience problems? I never did in the five plus years I ran one that way.
Also, the "extra" overall width actually puts the rear track exactly the same as the front track of factory disk brake cars.
...and 65-67 axles are about 1/3 to 1/5 the cost of an A body 8 3/4 and WAY (WAY) more plentiful.
