Height of a Skyliners open trunklid?

[hrsky]

Hi.  I'm in the process of rebuilding my garage and want it to be so high that I can retract the roof of my Skyliner inside it.  Unfortunately the roof doesn't work right now so I can not measure it.   Does anybody know the total height when the trunklid is open? Thanks in advance. HR.

With the tray extended you will probably need 10' or more.
I removed the roof from one of mine in a shop with 10' walls.
