Anyone got their headlining out. Need measurement

Hi guys

I'm retrofitting a rear head lining in my hardtop defender 90. I wondered if anyone has their headlining removed and would be kind enough to get a measurement for me?

I'm looking for the size of the brackets above the rear door that holds the rear 'Phone piece' shaped headliner. How much do they stand off the rear of the roof?

Thankyou
