I'm getting ready to buy replacement leaf springs for my 1975 Nova. It has the originals on it now which are 6 leaf. Classic Industries has replacements but they don't have 6 leaf, they do have 5 leaf replacements. Will it matter if I put 5 leaf springs instead of 6 leaf springs? I want the original ride height. JC Whitney does have 6 Leaf Replacement springs for my year Nova, they are John R. Spring brand, has anyone ever heard of these? Does anyone have any suggestions on what brand of springs I should go with, I'm willing to pay a little more for something of good quality. Thanks for the help.
