I hate to keep prefacing everything with 'I don't know about a
Love Bug,' but just want you to know that I am guessing.
It appears to me that it has shrunk over the years. My guess is that it met at one point in time. If it's not leaking, then I wouldn't worry about it. If it is, then when you replace it, I would 'push' the new piece on rather than 'pull' it on. Does that make sense? That would pervent it from shrinking so much in the future.
Ray just replaced the window in a
U-Haul, so he can probably help on this one.
BTW, I think it was very clear. I just wanted to make sure my brain absorbed it correctly. It does malfunction at times. ;)
