A lug nut cover (along with the nut) fell off my Ford e450 Class C (Fleetwood Tioga 29V) motor home. I've tried researching Google, this forum, and others to see about a replacement part. Does anyone have a suggestion or perhaps a similar year Ford e450 that has had to replace one before? Thanks! Dimensions are 1 5/8 cover length, 1 3/8 cover diameter, 1 1/16 lug nut outer diameter, and 9/16 thread hole.
