I'll post the part number up when I get home and maybe someone might know what it's from. It's already got two long bits cut off it because it was fitted to a Val before hand. But those parts I would've cut off anyway. I'll get a pic up later what they should look like. $170 the cost second hand and there is two nicks in one of the fans but no big drama.
Good stuff... i'm still contemplating just going with the 1 big thermo, but if I can find another set like this - looks like they'll fit like.... a set of MB Twin Thermo's..
