Got the truck looking good last year...then baseball sized hail hammered it in July of 2017. Thankfully I kept the comprehensive coverage.
Talked with the local GM body shop and got estimate on rockers...
The Big Block is currently in the shop getting hail fixed, rockers replaced, and three new speakers (blew out rear, and both a-pillar speakers).
Here is the replacement they gave me...2018 CC LT, All-Star edition 5.3/6spd. It's a nice truck...but it's not the Big Block : )
