Leaking Windshield Gasket
X2!
The 67 year trim is a lockstip (expensive) that install into the gasket to lock the gasket in.
your 68/69 has a self locking flap (zipper) that gets tucked into the gasket for self locking! The trim is known as reviel molding and is held in with clips that rust after a long time.
The 68/69 was a less expensive alternative to the 67 lockstip.
the 2 door non post cars windshield reproduced gaskets are available.
You can do a search on my screen name and look up 67 windshield and I have started or contributed to several threads and I have one with step by step install pics.
DISCLAIMER!!!: The experiance I am spewing like no bodies business is related to DARTS only and I only know very little Baracuda theory and no practical experience with them, but should be bout the same!
Someone with more experiance than me will come on board later today, so give it a bit, and the help will come in!!8)
