I am looking for replacement springs for my 69 z28. Does anyone manufacture an original looking spring and how many leafs were standard? Mine has 5 leafs but may have been altered. I understand the originals were not painted. Second question is should I look at having mine rearced? I understand rearced is having the main spring replaced, I would appreciate any help or comments. I am doing a total restoration on this car and trying to keep it orginal.
