Mike, it should be evident from the Dealer cars with Mohair hoods what the quality and fit is like. The latest spec of hood with folding frame, and the two lock down pins along the rear edge is excellent. The Simmonds easy fit hood was designed to improve the original design factory hood which is best identified by the row of fasteners along the top edge of the windscreen frame. These hoods also have a row of fasteners along the top edge of each rear wing, whereas the later hoods only have one lift-the-dot, and look 'much tidier'. On a personal note I also prefer the shape of the single rear window on the latest factory hood.
