Differential narrowing in/near Los Angeles 8.75 to A-body size shops needed

Another DTLA-er. I just built my 8.75 and also live in DTLA. I used a shop in east LA 10 mins away that had really good prices build me a 3.55 with eaton trutrac. I brought the housing, axles, and crusty JY 489 center section to them and left with a shiny, built 8.75. They had the 3.55 gears and trutrac in stock for the 489 too, it was done in a day and a half after dropping off. They also shortened my driveshaft quickly. All of this was done for hundreds less than everywhere else quoted.

More importantly to you I had asked if they could shorten a housing for me when I was searching. They said yes and i think it was fairly cheap ($100 or something?). If I were you I would get some dr diff axle in the width you want and bring the housing to them and tell them what you want. I ended up finding an A body housing but I know they are capable of what you need.

The name of the shop is Alcantars drivetrain performance. It looks like not much on the outside but TONS of stuff inside and they work quick. I think their specialty is jeeps and dana stuff.
