Ok this might sound stupid but I have a 75 westy and have the original over cab bunk was going to put it up when camping just for storage more then anything but I can’t get the headrests out the way . Have tried the normal pulling but they don’t seem to want to move can’t see any sort of clips like they have in the t25 any help with be great.
It's brutal but I ended up levering the driver's side up with a long piece of 3x2. You might need to take the seat out but mine worked with the end of the plank on the sink cabinet. They are just a tight fit, no clips.
