Hi guys. I have a 1970 Dearborn R code 4 speed car. I no longer have the stock rear leaf springs. I bought a new set from NPD, stripped them, and painted them the Zinc Phosphate from Eastwood. Could one of you please tell me what color(s) and the location of the marks I should add to my springs. In addition, are there identifying marks on the rear end/differential that I need to apply? Thanks in advance for your help and time. If possible, pictures would be AMAZING!
