Kirban Performance has the Welting Material for the flares and it was really simple. Tedious yet simple.
I added flares July 2012.
I added the Vents and used tape on one side and the tape held the heat in and burnt the metal using fan and air preesure for cooling metal, yet on the other side, we didn't tape it... just draw the line and cut... custom ASC Conversion in Little Chute, Wisconsin at Tim & Jay's Automotive...
Tim & Jay worked at the ORIGINAL Buick Dealership when the Turbo Regal/Grand Nationals were for sale 25 years ago. Tim owns a 70 Chevelle in low 9's he has owned since High School. And Jay is into Crotch Rockets and he isn't afraid to push it over 160 mph... I am lucky to have local Mechanics I trust with old or new cars...
