CIMA gearbox

I wonder if anyone has used a CIMA gearbox in GT40 or other midengine replica. I still have a Cima box and consider to use it in a future build but wonder whether it will fit from the dimensions and whether other guys have experience with the installation and performance of the box. I have seen old threads with Wanni on this but never saw an actual car with this box. I attach my pics for reference.
