D.U.I. Distributors in Tenn. Question

Performance Distributors (DUI)....Does anyone know if they are still open ? I have been trying to buy a Distributor through a 2nd party (Summit) and I thought they (Summit) were putting me off saying that they could not get in touch with them. I have bought 2 other units from them with great results and need another. I even called them with no answer. Not really complaining but I do not know of anyone else that has a better product (my opinion) for my Daughter's 65 Barracuda. Anyone else do a good job with custom set up for SB Mopar with firewall clearance and spark without Box, etc, etc ? Thanks Tim
