My experience with 100-4s is very limited. I purchased a '55 BN1 earlier this year. It is a total basket case and needs rear springs. I have some decent 100-6 leaf springs that I was assuming I could use. All this discussion about 100 springs has me wondering if there is something dimensionally different so that I cannot use the 100-6 leaf springs that I already have?</div>
