SW20 ARC side mounts

hey guys,
 
in the not too distant future I'll be looking to acquire two of the above to cut/weld together into a custom vertical core FMIC for my project.  i'm a mad ARC fan boy and the SW20 SMIC has the best dimensions to do this.
 
just wondering how easy it is to find these in aus.  i'm no stranger to yahoo japan and there're two on eBay in the US now anyway, but I'm just curious.
 
secondly, if anyone has one of these, I would be stoked if you could get me correct core dimensions.
 
cheers

That's definitely an ARC cooler - ARC part number tag, and tapered inlets to the tubes.  Good bit of gear.
 
Unfortunately further research has found me just one model better suited - Mazda Cosmo (think 20b).  same size, but thicker 105mm core.  Thanks anyway dude.
