If you still have a copy of GW, use SH3 Extractor to get all the TGA files out of their DAT files. I say GW because these are still at 2048x2048 and you can work better with them. GWX TGA files are at 1024x1024.
You can find the link for SH3 Extractor in the MODS & TOOLS sticky.
To get you started check my Filefront Account, you should find all the default textures for the Type 9 there and they are already arranged for JSGME.

LOL - I've even got SH3 Extractor too

I packed the type 9 skins together for a promising skinner who has now taken up moderating rather than filling this forum with skins. Shame
