.. yes you are correct The width is almost the same. It is 1-1/4" narrower then the D35. This is a very minor draw back, and
will work if you have wheels with less back-space then stock. If you have stock wheel back-spacing,
there are commercially hub-centric wheel spacers available..1-1/4" hub centric wheel spacers is what you will need.Also if you are going to refresh your axle here is some information that you might need :Other Parts Needed
