These are spacers I made to be able to install a spare tire delete plate on my Jeep JK without having to remove the vents. Delete plate instructions say to remove the vents but then you end up with big opening where water and bugs can enter the car so I thought what I could do, tested putting plate with vents and say screws are long enough but spacers provide a stop for the screws to prevent movement of the plate and noise when closing tailgate.
1/2x1/2 with 3/8 diameter wole thru the middle to insert factory spare tire carrier screw
p.s.: sorry, initial files were uploaded before using them on my Jeep yet and whole diameter was actually 1/4 and wouldn't allow the screw to fit. I've replaced all files with 3/8 diameter whole (see finished product installed on my jeep on picture).
