Welcome.

I have a 68 and 72 but no extra dash pads.
I wanna say good luck w/o sounding like a dink.

Keep an eye on eBay.
National Parts Depot may have one.
LMC Truck
Dennis Carpenter has all the old Ford toolings but thay also want a mint for there parts.

Also put a post in the 68-72 forum. There might be someone in that area that might have one.

also wanted to add that these trucks don't look half bad w/o the dash on it. With just the painted metal dash.
