Check this out.........I think this is the 51 plastic. The plastic looks like an above average used one. I'll take 10.00 including mailing costs in a bubble wrap bag.
If you want it, email me and let me know. You can pay with Paypal or send a money order.
I also have a lot of NOS and good used 49-51 Ford parts. I may have the chrome nut, will look for it in my parts.
Thanks, Paul
