I need some help trying to figure out what to do about getting new springs on my 71 Mach1. I want to get 620 coils up from(1 in lowering) and i also want to get new 5 leaf springs in the back but i do not know wether to go with mid eye or reverse eye springs. I have a new set of kyb shocks( right now i only have them installed on the front). the front sits higher right now due to the saggy 4 leafs and the worn out shocks on the back. I want the car to be atleast even all the way around but having the front sitting a tiny bit lower would be nice. I dont know what kind of difference the 5 leafs would make compared to the 4. and i also do not know how it will differ with the different eye settings. So does anyone have any suggestions on what springs to get to have the stance that I want. Thanks.
