Anyone know? I don't want to buy a bunch of sizes I will never use, and I don't want to go to the store more than once.

I searched and did not find anything.

 

i cant remember the size, at most autparts store on the help aisle you can get an assortment pack and 1 of them will fit it.

i've kinda said screw it when i lose them tho, i use an electrical eyelet...cut it from the connector and squeeze it onto the slot. works fine

 

it's about this big: |......|

(obvious jokes are not allowed, especially from you)

we have individual ones in the back at work... when I get to garfinkle's i'll grab mine and measure it.

or just drill a hole and use a cotter pin or something...

 

The rod diameter is 6mm, and the groove diameter is 5.25, if that helps. See
