ragtop care

Hello everyone, I have just purchased a 72 LeMans Sport Convertible, that has a brand new top, and I would like to know if anyone can offer me any tips on how to care for it and keep it nice. I am also looking for tips on setting up the car with a 70 nose, as well as looking for parts to be able to do so. Any suggestions or advise would be appreciated. This is my First GM project, and could use some good sound advise. Thanks. Brent
