Normal,
I've created a fully removable scuttle (interchangable aero & full screens), and regularly remove mine for wiring/dashboard jobs.
You will find the wiper system can be a bit awkward to get out, and you'll have to disconnect the speedo cable , then, if you don't have a heater (I don't think there is room for one under your bonnet is their?) the scuttle can be removed along with the front panel. Undo the 2 nuts each side where the scuttle joins the body, and the bolts that pass through holding the steering column in place, and it should, with a little persuasion, lift off. If will probably be held by some mastic along the front edge, but this can be peeled off, and doesn't seem to increase the amount of water entering the car when it rains .
Hope this helps,
Dave H
