This sale is for 4 towers, 2 crossbars, 2 bike trays, all made buy Yakima.  This is a great rack that served me well for my car and later my truck.  Now married with kids and minivan, I have no need for such frivolous equipment.
You choose a set of  [Double Cross Towers] OR [SST Towers].
The sale is for one set of 4 towers.

If you pick the SST tower, you choose a set of 4 each of [Y20 Clips] OR [Y30 Clips].
The sale is for one set of 4 Clips only with SST.

What you see in the pictures is what you will select.  Note that the trays are bent, and that the vinyl on one of the cross bars has a tear.  The pictures of the rack are at the least appealing angles, to show imperfections .  In spite of the rack not looking new it is structurally sound and served me well for many years in it's current state.  I am a fat daddy now, don't ride anymore, and need milk money.
Help with fitting your car.  The SST was on a Saturn but, there seems to be many other fits at this site.  The Double Cross was on a 95 Chevy Blazer, will fit many others.

Willing to breakout clips and sell them separatly.

SST Towers, Y20, Y30 Clipsss
