8 3/4 rear help

you can send the housing to moser or strange and they will narrow it up correctly for not that much money. you can get your housing narrowed and a set of axels for less than $400

a-body housings are getting harder to find and costing more money. if your rear is complete I would just have it shortened. If it was me i would have them go 1" narrower then stock a body. that makes a 8" wide rim with 4.5" bs fit perfect. that is the most common/cheapest wheel spec out there,.
