Cand J have a history of this. HE had issue then pulled in partners which went west, then packed up and moved on to Arizona i think you can try to call bill who is The New C&J Racing Frames for the last year or so (Bill) (928-377-1980) i dont think you where dealing with Jeff if this is in the last 12-24 months There number in North Carolina was 704-929-3978
Other person on the groundi think might be able to help you is Bob Neilson, i know he got burned with Dick fox and Shell, so he isnt fond of business scammers, he has good contacts in FT and would be able to locate him through guys like lineaweaver or Hos. ( Or even talk to Dale direct just email him - think his web site is dlineaweaver.com or somthing, just do a search for dale lineaweaver tuning, he'll track him down as he has done it before.
IF you can get your money back do, but youll ned to find out who actually cashed your cheque, and then get you coin back and buy a J & M Frame, turn around is only weeks. Good luck.
