These were on mi 76 when i got it but i've gone back to stock dash.
There is the wide plate that blocks off the heater controls & another to cover the glove box.
Also is a plate to block off the cowl inlet for the fresh air inlet and 2 hex plates to block the air ducts in the firewall. Note that the glove box cover has 2 small round dents.
Sell the works for $50 or can separate if needed. Shipping not included.

Interesting.

Gets rid of the heater and the glove box......... a tough sell in Texas these days......

the glove box cover is not a blanking plate, just fits the box front face so retains box access.
