Sc2 / Tekken 4 Stick mods -- more info?

I’ve seen a couple of REALLY old threads about modding these. I understand that you have to desolder the PCB, swap the buttons, and then bend the plugs or something to stick the pcb back on.

But I’m also looking for info on how to change the stick to a jlf, as well as some pictures or more step by step instructions. Does anyone have links to some old threads about this or possibly a detailed faq? It’s kinda hard to search for since ‘sc2’ and the number ‘4’ aren’t things you can easily use srk search for.
