I do believe these exist as I recently fought one at the local U-Pull-It
to get access to the shifter linkage on a 7/74 Bus.  If I remember there
were three 10mm bolts holding the pan on (it looks like a shallow
wheel barrow pan without the wheels) with a small sheet metal dimple where
the bottom of the steering box went.

I remember my old 69 Westie had one as we improvised one winter
when living in N.Carolina and used said pan as a snow sled for my
then smallish daughter.... She loved it!
