I used a remote reservoir kit as well in my 59 Suburban, not sure what I will end up with on the 58 2-ton, probably glue the carpet to some thick pad and as mentioned above, just pull it back when I need to check the master Cyl. Gluing the carpet to some thick jute pad (heavier fiber/hair type, not rubber) will make it lay a lot more like a rubber floor mat and not bunch up or wrinkle.
