The rear was pretty easy.
Lift and jack up the Vette.
Remove tires.
Remove monospring. Four bolts at the pumpking
and a bolt at each knuckle.
Remove shocks.
Remove mounting plate from shocks (upper). You need to re-use the plates for the coilovers.
No frame modification required.
You can't see it here but, I flipped the upper connecting rod's bolt.
It cleared but it was a bit too close for my taste.. Just being safe.
Rear Compression and rebound settings done for my driving needs.
Final look
