Take a look at Mill Supply.
https://www.millsupply.com/auto-body...pickup-sierra/

The slip over panels are 22ga. 22ga is miserable to weld on a good day and they don't have any of the base of the A, B, & C pillar sections that commonly rot away on vehicles.
The OE panels from Mill Supply don't state what gauge steel they use. I would request clarification on that before purchase.

There are commercial crash part suppliers that you may be able to purchase from. If Mill Supply doesn't use 18ga steel for their OE style rocker repair panels I would do some leg work. Talk to some body shops about who they purchase decent quality repair panels from. Worst case they tell you to take a hike.
