"I wonder if they have the same surface pattern as an original 61 piece"
Rstreet,
There is someone marketing a repo dash piece for a '61 now. I bought one just to see what the quality was. The piece looks nice but the black lines are twice as wide as the factory peice. Also, at this time, they are only making the main piece, no ash tray cover or glove box cover so until they repo those peices, it's useless because of the width of the lines.
The guy did tell me that they were working on the other two pieces. When all 3 pieces are available, they won't look too bad cause the line width won't be so noticable.
