The driver side seat in my 89 740 GL was difficult to adjust forward and backwards, so I removed it to take a look. The seats are non-electric. Sure enough there was lots of rust and built up grime on the rails so I separated them to better clean and lube. While doing this 4 steel rods and some small ball bearings fell out unto the lawn where I was working. The rods were easy to find but I only found one of the ball bearings which is roughly 3 mm in size. I want to reassemble but I'm wondering where i can find these ball bearings. I believe it takes 8 total. My usual approach has been to go to the junkyard and get what I need so I checked the local salvage yards and I could not find one single 740 to pull from. Anyone have recommendations for my dilemna.
