Bronze bushing  5mm x 3/32" Flanged.  Glue these into the rear pod of  your Ninco Lightning cars to get rid of the severe bushing looseness that plagues these cars.  They are a nice, tight fit, getting rid of all the slop.  These single-flanged bushings are also commonly used in brass or steel chassis where you just have a hole in the chassis for each bushing and the axles do not snap in and out.  They can be soldered in place. They can also be super glued into metal or plastic chassis.  Widely used by chassis scratchbuilders.  Outer diameter (not including flange) is 5mm, which is slightly larger than the 3/16" o.d. (4.7625mm) bushings commonly used in American commercial track racing.
