duster, demon, dart sport window louvers. Reproduction?

Yes. $300 was the going price from before 2000 - through-2012ish.
Inflation, material cost, labor, shipping-

The dollar menu is gone.

Inflation is no joke. The groceries I bought in 2005 practically doubled in cost by 2015.

Some of us rural folks are still purchasing cars with 1990’s prices, that doesn’t mean the value isn’t higher.

I totally agree.. Right now for my to get the amc material here is close to 300 to make an aluminum louver, That is not the rivets, hardware, mounting hinges, u channel metal edge or the push on trim seal on the sides. It all adds up. That is before an ounce of labor.. I will be selling the amc louvers for around 600 bare or more if powder coat. Duster and roadrunner ones will probably be around the same. I just paid 900 for a dales cuda shop louver for my e body cuda.
