I ended up buying the Ames FN377 cable only to find out they are the same. So, now I have a spare cable (LOL) and during the research process I found out that it is my carpet/sound insulation that keeps me to get WOT. I'm about 5/16" shy from the secondaries to open 90 degrees. In my opinion the gas pedal is way to low and not far enough form the floor to begin with, so...I will make an attempt to take the gas pedal assembly apart this WE and try to bend the pedal rod upward about 1/2" to gain height and be able to get the WOT. If anyone has any other suggestion how to adjust let me know.
I pulled the cable out where it attaches to the gas peddle and attached a small lead slip sinker on top of the end piece and then reattached it. It took out enough slack to allow mine to open. May want to try it. It has worked well.
