Part # Question

[mato27]

What is the difference between these two part #'s?

 

19202900 is listed on GMpartsdirect for the Black 6" step 07-09 Silverado Ext Cab

 

But, searching on the internet 19159771 is also listed as a Black 6" step 07-09 Silverado Ext Cab

 

Anyone know if there is a difference?

I had the dame issues with the 3" oval steps 2 months ago. I know that that GM just went through a part number change for the the 3" black steps.(at least that is what gmparts direct told me) They had a batch of older ones that they were selling 50% off because they could not sell them with the new part number??? I went ahead and got them and they fit perfect. They might have changed the part number on the 6" steps to.
