I had to disassemble my 69 tilt column (a real treat!) due to the little starter "rack and pinion" breaking. I got a new one and fixed it, but the upper column shaft bearing came apart. The web is plastic and is shot, so little balls went all over. I put some back and it's driveable, but I need to replace that bearing. Called a chevy dealer and got the run-around. Can't find it in any of the repro catalogs. Anyone have a tip?
