I ordered some custom made mounts to swap a 1JZ into a MZ10.
They are made to fit a 1JZ into any car that had an M series engine. That being said they might not quite fit your purpose. Possily could be adapted though??
B.T.W. I currently have a MA70 halfcut at the moment I could get some measurements off it if you want just a matter of waiting a little however as the engine will be in there for a little while yet.
