As I move "on" in years (yes, I'm getting old LOL), I cannot remember the sequence of front bench seat backs on the 1969-1972 split front benches. 1. Burlap over the bare springs 2. Cotton batting 3. Cheesecloth (I cannot remember the name for this material but it resembles cheesecloth) 4. slide the cover over while using a trash bag.. HOWEVER There are some small pieces of foam, there is a screw with a large washer that goes in the corner.. IF I was doing the base, it would be easy as pie... or buckets... It's just these damn seat backs. Thank you
