Drivetrain 8.8 Axle Rebuild

Morning folks. Still gathering parts to do a 5 lug conversion, went a bit astray and thought why not do new gears while I'm at it, better yet, why don't I get another rear end, swap in all the goodies (new gears, axles, brakes etc, etc) to make it easier on swap day, whenever that might be. So I have a Trac-lok 8.8 from an 89 hatch (that's what it came out of, not sure what year the axle actually is but that's a whole different subject) It has some other suspension brackets, maybe for a traction bar of some sort that I'll pull off as it's a bolt on.

But my question is, does anyone know a reputable shop in / around the Lowell MA. area (Southern NH too) that I can take this to for A) bead-blasting to clean it up and B) to install new gears in? I can install all the other stuff myself but I've never done a differential, don't want to start now.

Let me know

Thanks

Good Afternoon folks. 5L5, thank you for the information, sorry that my response is so delayed. That being said I've had a few minutes to take a look at the Axle and noticed some "extra" brackets, which I'm including pictures of. Since I'm not planning on upgrading the rear suspension, other than when I swap the rear out putting in new bushings and hardware. But rather than rip and toss I'm wondering if anyone knows what these might be for and whether I should keep, donate or toss. Let me know what folks think. If I need more pics I can do that.
