Thats the A3 engine deck, and Imperial Modellbau in Europe has it, along with a few other bits to convert the Tamiya to A3 configuration. I cannot remember their link, but the Gernam link I googled was NOT them.

I thought that Nick down in the US (maker of some excellent turrets and hulls for the sherman) also made this piece, but I'm not 100% positive. Anyone able to confirm this?
