Hi, everyone..just joined today in search of some answers. I have a 72 k5, the floor pans in the front are shot. I just got my beard seats in today and pulled up the mat to see noting but rot. To ensure I will have solid floor in the years to come..what parts do I need to replace and have a solid floor board. I know floor pans themselves but I got on a restoration site and there were rockers and support boxes. I just need some insight with what i am looking at. Thanks for anyone who helps!
