Hi Terry,
These Do Dads are a mixed blessing

. PERFECTLY adjusted (by bending) with a PERFECTLY fitting top, and PERFECTLY adjusted vent window tops, they may, or may not work for a while

. Usually, they help trap the top flap (pinching it) between the frame and vent window chrome

. Big problem is that the spring is not strong enough, and the top fit varies with temperature and humidity. AGAaaH!!!

I have lived with these Groinker Units for more tha 40 years now with my Veloce. I have found that those with much time fooling with these things use a forefinger to push them out with the window open, then close the window

. This workes fine for the driver, but passengers never can figure it out and the top gets damaged on the passenger side

. When a upholsterer replaces the top, they can never figure out how it was SUPPOSED to work, or fit INTO the top

. Many are left out intentionally

.
Check with "World Upholstery" to see if they have a spare. OR MAKE one

.
Don't worry if it does not work well. They never did!

Best,

Gordon Raymond
