In doing some work on my '69 Z/28 I find that my shackles are bent (I believe from an accident long, long ago). I have several extra sets sitting around which appear to be identical (just not bent). Is there only one shackle for all 1st gens regardless of configuration (i.e. Z/28, L6, BB, etc.)? I am referencing PN 3830840 shown on UPC4 page B2 of the AIM. I have a GM parts catalog from Dec '71 which shows one "repair kit" for the rear shackles on all 67-69 cars...PN 3849248. Thanks in advance.
PS does anyone know if Firebirds use the same part or is it different?
