I know that there is a company in California that will "restore" your Blazer to what ever extent you want.
http://www.gmtruckcenter.com/. One of the guys on ColoradoK5 had his done there. It looked really nice. Since then, he has sold it though. I have also come across another place that will restore trucks. Either you provide the truck or they will find one for you. It was very expensive though.
