So I'm realizing lowering spring options for early first gen escorts are very limited. I've located a new set that says they are for 9/80 - 4/83 ford escort 1.6" drop. I have a 6/83 wagon. I realize there's some extra weight in the back due to being wagon but other than this should I be able to use the springs? Is there a mounting, suspension, or other difference between 4/83 and 6/83 that would not allow them to fit without modification? Any help much appreciated, thanks!
