Cool, I'll watch his thread with interest. Could you maybe take some photos of the process and post them here?
I'm thinking of doing this over the winter. If you haven't bought your sides already you may be lucky and get seals with them. You will also require all the brackets to fix the sides to the tub, I contacted LR for a price and for the whole kit it's about £100, I can email you the list of parts if you need it.
