Welcome to RWG! Ambitious start The 160x used 1560/1570 movements, so those will fit. Given that you're intending to use a Yuki dial, are you however sure that you need to put out $$$ and insecurity for the old vintage gen movement? I would at least recommend you getting a movement ring for say a slow best eta movement. I have a 16013 midcase for sale here btw if you're interested, think it would be way better than a 5500 case at least...
