Ed - I have never disassembled an ACA product, so take this with a grain of salt - or a huge Margarita!
To get the boot cowl off, you of course need to remove the engine. That is not a huge deal, but it is probably way, way harder than hiring a small person to simply go in there.
Pretty sure you have to remove the windshield. In most models of the Dec, that apparently requires removing the wings!
Try this: open up the bottom. Remove the front seat and the floorboards (easy; I just did it this year). Get a creepy crawley with a back support, and do it from underneath. Carefully rebuild your master cylinders while you are at it.
Really easy to get to the sides of the boot cowl that way, too.
