Neo AES Pal to NTSC mod

OK, I'm working out a trade with someone at another message board, and they have a PAL Neo Geo. They told me there's an easy mod, which I googled and found here:

Unfortunately, I know nothing about electronics so this is basically Greek to me. Is this a difficult mod? And where can I get a video sync crystal/how much does it cost?

eh? Why do you want to change the region? Aes's are multi-regional.

He wants to change the broadcast format from PAL to NTSC.

Yes - it's a US guy after a NTSC output, plus the mods will also to 50Hz (slow with borders) to 60Hz fullscreen and full speed.

Oh right, not heard of that mod before.
