What parts do the official arcades for VF use?

Do the official Virtua Fighter cabinets use Sanwa or Seimitsu parts?

Am learning how to build my own arcade controllers by padhacking and soldering the arcade controls onto a sacreficed controllers PCB board, would love to build a Virtua Fighter specific arcade controller.

I already know that the layout is that of the first player Sega Astro City cab layout. Just with the left button of the bottom row and the two left buttons of the top row in there.


Just can't find any info if the official arcade version uses Sanwa or Seimitsu parts, or is it varied and doesnt matter?
