There is a long discussion about this, with lots of pictures, over on Lance's forum.
I believe his focus, right now, at least until he gets a answer is adapting a 157 flywheel and a front mount starter, that will bolt to it. Has anyone done that?
From the pictures, I believe he has a 5.5" triple disk clutch in it, attached to a 184 tooth FW right now. It hangs, unprotected, way down, below the chassis.
At this late date, I don't believe there is a bellhousing available (new or used) to connect a FE, to a Hewland LG 500 gearbox using a rear mount starter.
I hope that helps.
