I think that '52-'56 are the same on the firewall block off plate but the dash block off is '54 only.

Unless you want 100% original, it probably will be cheaper, and faster, to have them made. 

Yes, I want 100% original.  I have a temporary one on the car now that I made myself but it doesn't look exactly like the original should.

Allen,
I might have the blank off plate for the heater control on the dash.
I’ll Dig it out and send a photo

i did see a fire wall one on eBay but it was for a f 250

Do you have documentation that proves that's how the car was originally equipped?

Allen,
I found it.

Hey Black Tie…
Lighten up!
Allen is building a 1954 Ford  Mainline California Highway Patrol Cruiser. It’s a very unique undertaking, complete with siren, red lights, radio, black paint, white door with period CHP Logo. 

Hi Richard.  I sent you a PM two days ago but I haven't heard from you.  Please contact me so I can arrange to buy the block off plate from you.  Thanks, Alan (805) 205-4470 or alanfreeman54@gmail.com

Thanks Richard for the dash block off plate.  I am still looking for the firewall block off.
