This is a manual transmission bellhousing for the Ford FE engines, 352-428, for pickup 4-speeds, or small block toploaders.  It is about 1/4" deeper than the car bellhousing, which is perfect for the longer snout on the small block toploader 4-speeds.  I purchased this in a lot of NOS Ford parts and appears to be NOS.  I cannot guarantee that but I'm not charging NOS price either.  It is in perfect shape.
