My deacl is in very weathered state and all I can really see is Part#3934882 or the second to last # could be 3.It is in tough shape. As far as the letters I can see an A but cannot make out the letter next to it. I see Jerrys white car has an AG on the decal,that is why I was wondering which Letters mine should be in cause I ever am able to locate one. I know they used AG and AY which yours is. Looks like Ricks only has the AG coded ones.
