Vanspeed - Good luck finding an original spring. When I took my front spring apart three of the leaves were broken. I had a heck of a time finding a decent spring, and ended up obtaining three others and scavenging good leaves from them. Also, often springs have grooves worn in the tops of the leaves from years of unlubricated movement of the leaf above. Those grooves should be ground out to enable smooth movement, and the leading lower edges of the leaves should have an angle ground into them so they don't act like chisels on the leaf below. I painted the rubbing surfaces of my leaves with graphite paint before reassembly.

If you're not set on "original", a reasonable alternative is the EATON Detroit 8-leaf equivalent to the 10-leaf spring. Same spring rate, but thicker leaves.

Unfortunately Travis Cook (A-Springs.com) is no longer making springs.
