I bought these for my Dave Scott Centurion, and although not perfect, they are close, https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1.
One of the white ones on my bike was pretty beat up, had tears on the top of the hood. Unless those are that shot, just give them a really good cleaning, let them dry, and if they are still a little tacky after drying put some talcum powder on them.
I bought these to replace Shimano 105's, which are not on your bike, but they might work.
