Ok guys, I'm gonna sound very stupid here but what is the difference between Styleside and Flareside and how do I know what my truck is?

 

Styleside is the 'regular' box, with the wheel wells inside the bed.
Flareside is the more 'stylish' box, reminiscent of the older pickups that used to have running boards and fenders outside the bed.

IIRC, the styleside comes in long and short bed versions, the flareside only in short bed.

 

ok, thanks, makes since now that I understand it. Thanks again.
