If you still have the slide cover hardware you can just buy the fabric from ToughTops
. I used them when our old ones needed replacing last year. Fairly cheap and fit perfectly. Friend and I did them in about an hour, and yes, you almost have to have two people. One to pull the fabric and the other to guide it.
