I drove my GS all the way home from near Seattle, to Fargo ND last fall, about 1400 miles, with double springs on the linkage. Man, what a pain. Now that I'm getting ready to take her out of winter storage, I'm going to pull one spring to ease up the load on the 41 yr old leg. Which one to leave on the car? One is about 7/8" diameter, and thicker rod. The other is only about 9/16" diameter, and considerably thinner rod. Is the lighter weight spring sufficient to provide enough resistance to the gas pedal? Would one of these be close to the original spec? What do others run, or do you all use doubles? I'll probably try out the heavier duty spring first, and see how it feels. Any input?
