Hello all,
Recently picked up a 88 Z24 Convertible in decent shape but it needs some odds n ends that are not available at your corner store anymore. Currently looking for the window belt weather strip moldings that are on the outside of the car at the bottom of each of the 4 windows. The rubber part that seals against the glass is hard and falling apart and they look horrible. Prefer brand new after market or NOS originals. Any info much appreciated!!!

They are nearly impossible to find. 1 Set just sold back in June. It was the only set I've seen for sale in years.
You can replace the felt sweeps though. You can get them at: https://www.steelerubber.com/beltline-weatherstripping
Just type in 70-3805-61 in their search box. These are the ones everyone has been using, though most of us got them from Danno, whom is now retired and no longer in business.
Steele rubber make excellent quality products. I've been to their factory in Denver, NC. Great folks there.

You can view this thread with pictures of where you'll need to be snip the belt to make the curve.

Here is a thread that has part numbers (though you are not very likely to find any) and information on installing new beltlines, but the pictures are gone now

You might try contacting Frank to see if he still has the pictures on his computer, if you need them.
