Narrowing 8-3/4" Rear Central PA

[roughidle]

Good morning everyone - while back on marketplace, possibly here, I remember seeing an advertisement for a guy in central or south central PA that was narrowing mopar 8-3/4" rear ends. More or less advertising different levels of performance. From the most basic bare rear end just narrowed to your specifications, to a fully built rear axle with gears, back bracing, disc brakes, etc.

I have since lost the contact information. If anyone knows who or where the guy may have been, OR if anyone has a reputable shop that could do this work, please let me know. Looking to have a rear narrowed slightly over the winter.

Thanks in advance!
