Take a look at the bullet catch, 10-053 , this is used with shower doors. Match up the dimensions with your original catch to see if it could work.
As for the sweep you could replace the complete sweep with a drip rail like, 10-324 . However, also check to see if you might be able to replace just the vinyl sweep itself, something like 10-327 or any others we have here: Lavatory Replacement Hardware |
