Yes, the original caps and strainers fit just like they originally did.I've been letting the buyers do what they want for a rubber covering. When I did mine I covered them with roofing ice barrier. It comes in 3' wide rolls, is between 1/16 and 1/8" thick, and once applied looks a lot like the original covering. But I have also seen people cover them with bed liner, and others with 1/4" thick rubber. I guess it's all what you like.Steve
