Working on the 3rd gen cars and have questions on the front springs. I had a set of 6 cyl springs that were old and weak. I got a pair of V8 springs from a friend. The wire size was smaller and they were less coils in them than the 6 cyl springs. Then I took a set of springs I had from a 71 V8 car with a/c and they are the same size as the 6 cyl springs. A friend who was a parts mgr for GM the past 25 yrs told me the 6 cyl springs were bigger than the V8 springs because the 6 cyl weighed more than the V8. Does anyone know the wire size and number ofcoils on springs in a 6 banger and a V8 then a V8 with air? Just curious about this.
