68 rear spring problems.......
Can someone here who knows 68's tell me what these springs are. They aren't stock i don't thing. The bands are in a strange place, and there are no curls at the end of the leaves. The car is too high, and rides like a buckboard. .....
The guys at the C1+2 forum aren't real familiar with the 3's, thanks.

our sponsor VBP sells a 7 leaf and says its 292 lb. Perhaps the same specs. The 7 leaf was usually the performance spring opposed to the 9 leaf.
To lower it, you need longer bolts and you let out on the nut and the car will lower.

How long have you had the car? New to you? Contact the seller and ask whether/when the rear spring may have been swapped. Can't really see much from the pix for identifying the spring. Could be afermarket; could be an over the counter service replacement spring from Chevrolet.

My first reaction is that you should remove those bands around the leaves. I believe they were supposed to be only for warehousing and shipping. Seems to me that they would bind up the leaves together and not allow them to really move past each other. The center mounting should hold the leaves in place. There is a bolt that goes through the middle of the spring to hold all the leaves together left and right. The four mounting bolts should keep the leaves from fanning out.

I have a '69 vett that I replaced the 9 leaf spring with an after market unit. I had the same ride height problem. First you need to remove those shipping bands. What I did to correct the ride height was swap the top three curved short leafs with the top three flat leafs from my factory spring. I reinstalled the spring with the factory 6" bolts. My vett
returned to the correct ride height.
when you tighten the mount bolts make sure they dont go through the bottom of the diff. case. good luck.
