Has anyone ever had experience with these shops? Shift SST recommended them as installation shops for my Magnum 6 speed.

Newcomer Racing

Im planning on having my transmission, driveshaft, and rearend all installed at once, so I need a shop that can do all of this. If anyone has used these shops, or has recommendations for NC shops in the charlotte area, please let me know.

Also, has anyone used prestige motorsport or hi tech motorsport? I just need a real performance shop that can install these things/test everything (pinion angle for example).

Even though no one's responded yet, I have one last shop that was recommended by Todd Marsh: Mark Dudley. Is he one of the best like Marsh says?

Anyone?

I have never had any work done by them (although I can say their beer and BBQ is good), Erik Yost and his Customs by Bigun have a great reputation.
