I went through this recently , I wound up getting good used springs from Mother Trucker as the repop ones are too long and near impossible to assemble too .

I'm still looking for the nifty sheet metal dust shields used on other GM products as those crappy
repop rubber ones rot away in 6 months . I suppose I could just cut a slab of rubber....

There is no problem so difficult it cannot be overcome by generous application of brute force & ignorance
