He isn’t in TX, but he is the best in the business and will do it with all the good hardware.
If you go cheap or with someone who doesn’t really know what they are doing, you may pay to get it done twice.

To OP-- 75 diff's have bad axles, ring gear bolts and clutches. There are many many place that will rebuild these, they are not rocket ships- then you would need Lars. However, as simple and basic as they are there are ways to improve the build so a lot depends on your objective now and in the future. If you are planning on a street car with low power and no abuse that is one application, if you have power, say 400+hp and plan on some abuse then that is a completely different application.
I would ask any place you speak with if they know of or use the following
1- USA Timken Bearings- while all well known brands should be made in ISO certified plants I would stick with Timken.
2- Axle bearing type- there are differences
3- Axle replacement type and endplay setup- Tip- a rebuilt diff with more then 010" endplay is not good.
4- Clutch type for the posi- solids, snowflakes, fiber?
5- Posi polishing and tuning. Do they check the case for cracks?
6 -Ring gear bolts used
7- Gears used if needed
8- Fit caps to what spec?
If you get answers to these questions that sound reasonable but sarcastic, well no they should not be sarcastic with a customer but who knows, then you will have a better feel for the guy. There is a huge difference in cookie cutter jobs and those that are more detailed for longer life.
Good luck.

- Spent what was probably one of the last Tuning for Beer weekends (in Northern Virginia) w/Lars where he tuned my car
- Gary has rebuilt my steering box, differential, trailing arm bearing assemblies and half shafts.
You will not find better, not saying there aren't others who might be as good, but you cannot go wrong with either of them when it comes to their specialties.
Yeah, it's going to cost you a good deal to ship, just suck it up and do it right the first time
