Franken saddle

Afternoon all. I have a couple of Charge Spoons and I want to put the white rails from the grey saddle onto the black one. It looks as though the rails are inserted into the hull and the cover is put on afterwards but I could be wrong.
I just wondered if it's possible to dismantle and re-assemble the saddles without trashing them.
TIA
