[FC] Rear Door Greenbrier Window Gaskets

[corvanatics@corvair.org]

The brier has cracked and leaking gaskets around the windows for the rear 
doors.  I bought a set of Clark's replacements, but have yet to install them.  
Has anyone performed this replacement?  With Clark's repros?  What was the 
success rate?  Problems?  Solutions?  Just looking to find out what I'm up against 
before I cut out the old ones....They leak a little, but do hold the glass in.

Thanks in advance for any information rendered,
