75x50 CLS, 686mm door. Door lining kit that fits?

[f0rmula]

Can anyone out there tell me where on earth I can buy a door lining kit that fits this configuration?(without having to chop it about).

My CLS finished is about 63mm, plus 12mm plasterboard, plus a 3mm skim. That comes to 93mm. No door lining kits seem to be anywhere near that narrow. And the ones that get close seem to be for 768 or 868mm doors

What would you guys do?

Cheers for any replies.

As you suggested you will have to rip down an off the shelf lining or make one up yourself.

Forgot to thank you for the reply. Cheers. I ended up doing exactly that.
