Im replacing springs because they are in baaaaaad shape. I cant find an exact match but found some that will work BUT. The pin that goes thru the middle I assume to hold the springs together, is that right? Anyway the pin was through backwards I think, never seen ones with the pin on top and the nut on bottom so I tried to take it off and turn around and it didnt want to come all the way off, monked up the threads the last couple threads. Is it supposed to be nut on bottom because it doesnt fit in the alignment hole. What is my options here?
