Need help.Was there a difference in the size of the front screens between an Oval convertible and a standard body?

Yes.
The convertible windscreen is much squarer than a standard body. Not sure on actual size measurement however notably different.

Thanks. Trying to buy the windscreen chrome moulding for my Oval.CIP site only lists 53-57 Vert. I thought perhaps Vert and standard Oval were identical. I see now they are different.

Wolfsburg West supplies window trim. Give them a try.
