Tips for fitting replacement Westfalia Headliner vinyl

1. How can I get these 'nuts' (not sure what these things are called) out without damaging the or the wood board


2. Best thing to get left over glue off the the boards left by the old vinyl

 

What I've done before to remove these "pronged tee nuts" is to screw a bolt in and tap gently from side to side working your way round and then, depending on which side you're on, either tap in or pull out. To remove the glue, which I suspect would be of the contact variety, use a sharp scraper as it will just clog sandpaper, you could try acetone to dissolve it but you would probably pass out from fumes before you got anywhere

I would also call them T nuts. Are you trying to save the nuts or the wood, or both?

 

"T nuts" may also refer to the following:-

Ordering a couple of dozen of the wrong type resulted in an expensive error

I have wondered what those are called - just the thing for type-4 alternator adjustment.

 

Thanks, I've tried a couple of the T nuts & they come out quite easily, I'm just wary because I have a habit of breaking things
As for the acetone approach, sounds interesting

 

The wood mostly, and maybe the T nuts but they can be replaced, screwfix etc do them
