63\" Springs I am thinking about buying a set of 63" Chevy springs (for the rear). They are 3 leaf with overload and shackles. Is this what I should be looking for? If so does $125 sound like a good deal for em? I found a set for sale and am gonna see if my boss (mom) will spot me some cash to get em. I already have the ORD 4" shackle flip too just for FYI. Thanks!
