Looking for assistance on JAMMA PCB Arcade 1up conversion

[Arcade-Projects]

I have a Namco System 12 board for the game Ehrgeiz. I have a Street Fighter II Arcade 1up cabinet. My goal is to be able to use the Ehrgeiz PCB on the Arcade 1up machine. I've seen people use the 60 in 1 JAMMAs but with the vertical machines. I'm not entirely sure if I have everything I need:

Everything below is what I have so far:

amazon.com/gp/product/B06X9NJ2…tle_o00_s00?ie=UTF8&psc=1

I'd also like to get this switcher in case I want more JAMMA boards: ebay.com/itm/6Way-6in1-Jamma-A…d869a9:g:HF0AAOSwsndbX13u

I was also planning on buying this to help me out: amazon.com/gp/product/B07D7HQM…smid=A14L2IPQKNJPJ2&psc=1

Is that pretty much everything I need? I've never done this before so any help would be super amazing.
