I don't think there is one with that firewall, My suggestion being, use a brand nu wheelbarrow for the firewall and mod to fit ur new engine. Of course you need to remove the frame from the barrow itsef ( Obviouse ), They measure up pretty good in 31 A's from what I'v read on the net. I looked at a page on someone who used a wheelbarrow and it showed him modding it but I cannot find the page now.
