I understand J C Whittney and others sell a multi leaf spring that will replace the factory single leaf springs. Has anyone here done this swap and if so are there any other parts or installation tips you could let me know about? Thanks in advance.

 

Should be a simple bolt in deal,some cars came OEM with them,Z28,SS,RS.

 

Installed Hotchkis leaf springs on our 1968 and I remember the bushing being hard to remove and install. I'd recommend installing new bushing with a small hydraulic press, even if it means taking it to a autoparts machine shop to have it done.
