Brian,
You're not in over your head.
There should me no mastic on the glass seal it would appear someone
used it rather than replace the seal. Try goof-off to get the old stuff off but
try
it in a hidden spot to make sure it doesn't eat the paint. Shouldn't because
you can use it to remove bumper stickers.
Mount the seal in the frame. Take some nylon rope (it's been a while) 1/8" to
1/4" and tuck it into the groove for the glass, all the way around. It should
overlap a little on the bottom and still leave you some to grab hold of. I did
mine from the outside of the car so the spare rope should be outside the
car. Lay the glass in the bottom groove. Have an assistant hold the glass
(my then 12 year old son helped me) and slowly but firmly pull out the rope.
As it pulls out from under the glass it will pull the gasket around the glass.
It's amazing how easy it really is.
Hope this helps,
Andy D.
