I had a Simmonds hood on a former car and as Graham says as long as you don't overfill the parcel shelf its not a problem, I learnt fairly quickly to put 'squidgy stuff' like coats in front of the clips and then its a simple thing to do. If you have a zip down rear window fitted at the same rime its even easier provided of course you specify the zip to be able to open from the outside. I was advised that's a security question but if someone wants in then a zip on the inside will not stop them will it? Makes for a pleasant day in extreme hot weather to have the hood up, sidescreens off and rear window zipped down! It will stop raining one day!
