Hi Orange!
I've found that even if it is a good fit, (mine is) then water can still get in. I have a constant problem with water getting in where the two seals meet at the top front of the drivers door. Sometimes I put a big blob of vasaline there - not attractive but it helps!

hi shel
nothing wrong with a blob of vasiline try anything once, but no such thing as water proof roof, but i always keep a check on floor to see how bad its getting.
and rustbucket i have had my floor out in one peice, tis indeed not a nice job but its the best way to see what state the floors and sills are in and its a way to spend the day lol
