Fitting replacement locker doors!

Sandgroper

Hi!

My Bailey Olympus 464 ( 2010) suffered from a locker door failure this summer. I have purchased a replacement Thetford door from Baileys and wonder bif anyone has fitted one?

There doesn't seem to be any mechanical fixing of the door surround and I suspect that the fixing is done simply be applying Sikaflex to the door face and usingits adhesive qualities to secure the door surround.

My problem is just how to apply sufficient pressure to remove the door surround prior to fitting the new. 

Any ideas??
