The 4 Dzus fasteners should be on the nosecone already. I spent a very dusty half hour or so with some emery cloth on the various cut outs for ARB and lower wishbone, in order to get the fit just right.
LADS top tip, bond or solder a washer into the slots of the bottom Dzus fasteners. Instant wing nuts, saves scrabbling around on your knees with a stubby screwdriver. LADS other top tip, secure another washer, with a twisty tie, to a brake pipe from the master cylinder. You can now remove the nosecone without any tools at all.
