About a year ago I had a new GAHH top installed. The other day I got to looking at the driver side and it didn't quite close right. So upon inspection I noticed the mushroom locking posts on the clamping piece were broken. Now plastic can be expected to do that after 20 years. So after researching and referring to Mike Focke's excellent top repair DIY's , ordered new parts from Pelican. I would recommend replacing these parts if you have a new top installed, cost was $85.00. One thing the DIY's point out is that the lower top needs to be disassembled to replace the slides, this is not correct as you can see by the pic. First side took about an hour to do, second was 20 minutes. I used the 3m super stick tape to attach the top fabric to the clamping piece. Should have no problem here for the next 20 years. On a side note after seeing how this top is designed, I will absolutely replace the top myself if I ever have to. Simplicity by design.
