There is no more info lol.

Only other way would be to weld in some sort of brace from one side of the rear quarter to the other and trying to fit the same sort of catches that a Saff would use. But the clamp point is about 3 inch higher than the rear parcel shelf so you would have to re-design the boot area for it to look good enough not to notice some massive bar welded in the rear.

Just use Granada cos rear seats. Same as what i had in my first RST.
