A friend has a 1988 Firebird with this option. Yesterday I explored why the hatch would not activate to lock the hatch.
After removing the necessary plastic upholstery, I checked out the assembly. It appears that the plastic "shims" just
plain rotted/warn away. Pieces in the bottom of truck.
The latch will not activate unless i pull the lit to towards me. Th heavy bristles will hold the latch in position.
I do that & hatch will lock closed.
Anyone have a solution for replacement "shims"?

 

You talking about sliders that the metal rails slide on?

This is where we all buy service parts kits for hatch, https://www.top-downsolutions.com/in...te=common/home

 

I bought the entire rebuild kit and it worked quite well

 

Tkx for the information. Much appreciated.
Passing off this information to the lady owner.

 

Is the clear plastic housing cracked as well? Almost every one of these that I’ve seen has a cracked housing or worse. I’d replace that as well. I didn’t see any from Lon the last time I checked. However, you can buy them new from that auction site. They’re not cheap, but you might as well fix it properly so she has no problems in the future.
