I am in the process of cutting mine off... But am at an early stage of refurb and will be replacing anyway.... i couldnt see any other way of getting them off.
It's a scary time removing belly pans :scared0016: as you don't know what you'll find
Mines got them, I haven't removed them but I did do a sneaky check, I borrowed a drain snake camera and popped it through the drain bung holes, creavases, and through a hole in the floor inside, prior to fitting my leg base for my table, and thankfully no hidden nasties 8)
