hey, tinlizzie69. We bought a '71 Overlander last year and, yes, as yours,the tambour doors under the sink area were falling apart. I pulled them out last summer (carefully, 'cause I thought I could maybe rebuild them). Lots of info on the forum about them. I think I would buy the new, if I were going to keep it original. At this point, I have spring-tension rods and fabric "drapes" for my doors. We've traveled NV to AK and haven't had a problem with stuff falling out of the shelves. I think I'll just keep them that way. Easy to access, for sure.
