Not sure where to get them, but mine came with a rubber mat...my duster was a cheap one to say the least. The rubber seemed to hold the moisture in too well...lol. If I come across something I will let you know.
Wow, I must say looks much nicer than before! Nice job I love it. So did you make those panels or did you order them fro somewhere? If so I would love to know where.
where would you be able to get it converted. I would always like a modern head unit but the nostalgic look is great :). That unit you picked up looks great btw!
