Technical Looking for specific Dallas area differential rebuilder

5 or 6 years ago, I talked to an outfit in the DFW area about rebuilding/modifying my Ford 9". I've lost their name/contact info. They were a large outfit, telling me they had many hundreds of used units in their back lot. They may have been in the Waxahachie area...can't remember for sure.
Does anyone know the name of the company I'm talking about? They've got to be unique because of their size.

 

Most of the 4WD shops will know people. They do more axle work than car shops.

 

I got the impression this was not a "shop" as such, more of a plant/factory that rebuilt differentials, specializing in the 9"

 

Paul Peyton was down near Ennis if I remember right.

 

Stan Hopkins in Pleasant Grove area of Dallas does good work. Had no problems working on our Model A coupe.

 

I'll check him out tomorrow. Thanks.
