All parts except the screws were junk I found lying around the garage.
The only modification to the bonnet is the four holes in the cross bar for the hinge screws. I've put a piece of wood inside the channel that they screw into.
The front bracket that the bolt goes into attaches via the existing bonnet latch bolts. It's made from 1.5mm galvanised steel. IIRC the centre of the bolt hole is 80mm from the bend in the bracket. It needs to be as high as possible otherwise the bolt hits the radiator cap when you try to close the bonnet (guess who discovered that the hard way and had to make a new bracket with the hole higher up?
).The rubber dome thingy is crucial: it fits into the wheel's centre hole and prevents the wheel sliding around. It's actually half of the head of a rubber mallet previously used for banging tent pegs into the ground. I held it on with Araldite Rapid and four long screws.
The spring on the bolt is there to make sure it can't vibrate loose. The bolt itself is bigger than it needs to be but it's just what I happened to have lying around. I slathered plenty of grease onto it to stop it rusting and seizing up.
I know it looks a bit 'scrapyard challenge' now, but it will be prettier once I get around to giving it a lick of paint.
I'm not intending to use the carrier every day - it's meant for when I'm going on a road trip with a passenger and really need that extra luggage space under the boot floor. I'm hoping I'll now be able to fit my tent, air bed, tools, spares, etc. under there!
