The over flow plate doesn't have a toggle in this case. You can see the rubber stopper sitting on the tub in the picture. The plate just has a threaded bolt that screws in to hold it in place. This looks just like my tub. The drum tap is very likely rusted to all hell and heat may need to be applied to even get it open. With mine, the threads were so rusted the cap was never going to be able to be put back on. Let me know if that is the case and I'll let you know how I fixed mine.
