Hi, When I got my RR the head lining was in two pieces in the boot. It was then sent to the bin big mistake I have no template now. I might be able to get another tatty one to use as a template.
I will also have a look at the Martin Motors GRP type. I did try to wash the head lining in my Disco it ended up drooping down. I used tin tacks to hold it back up, I might some time strip it all and paint the what ever it is under the cloth.
Why did the car manufacturers stop putting the nice washable vinyl head linings in motors, damp cloth and Bob,s your uncle
