1964 Valiant Single to Dual Master Swap Question

I have the original single pot in my 64 and picked up a Raybestos MC36338 after reading some swap stories and recommendations. After examining the part I noticed there are not two screw holes for the push rod retaining "stop" plate. Does this new dual cylinder have some way of capturing the rod or do I need to get a different dual cylinder for the swap? -Todd
