Installed carpet and insulation in the floor of my 58 3100 and now I notice that I can't get full throttle because the carpet takes up a half inch of my range.I'm on the floor and running between 65 and 70 but the carpet does not let me bottom out the gas pedal. Is there a way to extent the accelerator rod without welding to use the half inch that the carpet is stealing? I'm running a 55 235 with 3.90 rear and overdrive.
