HI Merv,
I was able to get the cobra on the hoist and fit karens mustang undernieth.
I cut one of the rafters out ( professionally) so that the windscreen and roll bar would fit up in the roof, had it all gyrrocked and insulated.
The roof was the standard 2600mm, I was able to stand under the cobra but I suppose I am a shortass.
Sorry could only find this pic.
