I have a pair of genuine side bars (the 3" polished stainless steel type), look a bit more wide boy than the normal steps!!
They are not for a 4 door. So either a club cab or single cab (but new shape, 2006>)
If anyone is after a pair I will take the sizes of the mounting brackets so you can compare against your fixing points. You will also need to check you have fixing points (90% do but not all)
