Reply to "Authentic hood mounting?"

Looking at it all a bit further, then it seems it’s inside and on top. There’s a hoop running round inside the top of the tub, over which the canvas threads. This is then clamped in place with simple tabs. Then there’s a flap on the outside of the hood that covers the gap between tub and hood. And then yes, the studs are only used for the tonneau. It doesn’t seem difficult to do - bend a tube/hoop to fit the tub, fit and get an upholsterer to sew on the flap. The existing material can be folded in to enclose the new hoop.
The primary advantage would be that raising the hood could all be done from inside the car, with only the snaps behind the door needing to be fastened. 
I think I’ll have a go soon...
