how to fit a corner bath panel?

Hi I have a corner bath panel which I am struggling to fit.
It's a Trojan Plastics Orlando Corner bath (see pics) - I'm not quite sure what I need to do in order to fit it under the bath. There are 5 wooden blocks distributed along the underside edge where I guess the clips would attach to. The problem I think I have got is the height of the bath is a little low and so I can only think of a couple of options:
1. Trim the panel at the bottom. I want to avoid doing this as it would mean the panel would no longer have the flat lip for it to rest on the floor.
2. Somehow trim the wooden blocks attached to the bath to give a little more height on the inside of the bath and attempt to bend the panel into place.

Any thoughts/suggestions/tips?
cheers

 

I've gone for the trim on the top so any uneven rough cutting is hidden and keeps the flat lip on the floor... now the only problem I have is working out how to get it to fit more snug - I'm thinking of making some sort of wedges on those wooden blocks so it can make a tighter fit.
