weatherstrip is held in place by "strip caulk" type material.........

not sure of the foam on the clips unless it was an upgrade to reduce rattles.....I've taken dozens of panels off and don't recall seeing the foam....that's not to say it wasn't there....could have turned to dust over the years when subject to years of heat, etc

install tips: go slow....make sure you have each clip lined up and semi-started in the cooresponding hole....use you hand to steadliy push in the clip....don't wack on it or you could cut thru the vinyl covering....ask me how i know....

others much smarter than me will probably be along soon with more help

I'd mostly seen the foam  tabs on old origional pony panels. Little 3/8" or so squares to assist holding the door clips in position.
Rick, I've just set the panels in position aligning the clip wire endsin their respective holes. The pop the clips into the doors witth the heel of your hand.

Tubo

 

to install watershields get a roll of 1/4" butyl tape at the auto parts store. I used Strip Calk and was less than pleased. The butyl tape is really sticky. The Strip Calk gets stuck together in the package and is hard to apply. The butyl can easily be laid out and the watershield attached to it. 

MS,

Cliff Claven called and wants you to call him back..............
