Purchased wheel wrench (£11). Verified that it worked (released wheel nuts on rear o/s). Dad advised remove wheel and gently tap the drum to release the shoes. Advised to avoid hitting it hard. Removed the clips from the rear hatch glass. Dad advised that I cut the rubber and use this to release the pressure on the trim for easy removal. Dad helped me to amend the instructions for first time starting (after lay-up). Dad advised to leave engine installed and clean up the engine bay instead – or at least try that first before removal.
