I'm no body man, but that'll be extremely hard if it is repairable...

I would say no...

 

I think that should buff right out...

 

Couple new windows + weatherstripping, new driver side rear bumper molding, new plastic pillar cover.....piece of cake.

 

What happened to that thing?!

 

Weird how the tail light survived.

Dunno what year or where, but try your craigslist https://houston.craigslist.org/pts/d...835363201.html

 

IMHO it could probably be fixed.

Either by pulling and straightenin the pillar, or by cutting the pillar and welding a new one in.
The GM parts catalog or LMC trucks body parts may show you if there is replacement parts.

A "good" body shop should be able to tell you.
If you want to keep it make a budget on what your Blazer is worth to you.
Many shops will tell you "it's a write-off" because the labor and parts are higher than the worth of the truck.

I had a similar damage on a Nissan Terrano once. The body shop told us that he will pull the pillar for a flat fee of 500 $ and from there determine if it can be fixed.
At the time the truck had a good 7'000 $ worth so we went with it.

Turned out the repair was possible with less work than expected.

Nevertheless it's a pillar which form part of the roll-over structure. Therefore a repair has to be made properly.
