I know alot of you guys have installed these on your trucks, and I think I read some place that you needed to use spacers when installing on a flareside. Is this true? Can you tell me if there is anything I need to know before I do the install. Thanks,

 

I used nylon washers from the hardware store.

Where did you put the spacers? Between the door and the sheet metal or behind the sheet metal?
