From what i can see it's missing the larger harmonic balancer and larger swaybar???
I noticed the bar as well, have better pics on their way but it is one of those items that would be odd to be swapped out for something smaller so worries me a bit
Trying to remember what else for the K to check (that I can see) - engine mounts, exhaust (original gone, has headers), Carby (gone, has holley I think), Diff to be checked, GB to be checked
Pulled of the RHS guard, so hopefully there are a few matching VINs
Still needs quite a bit of panel work as well (rear etc)
cheers
