These reclining seat gear transmissions are from an early model E32 735il. I was restoring a late model E32 740i 1994 and thought these would work for me however the seats were different. Pulled from a local junkyard, bead blasted, painted and greased. The gears inside are all metal, with only one gear made from plastic mated to a larger metal gear. They are ready to be installed and used.
