This is a bulk pack of 20 sets.
Here is a little breakdown of the Install for the Tacoma and Tundra style. 4Runner CMC pictures are displayed at the bottom of a page.
Tools needed
10mm wrench
Floor Jack
Jack Stands
4.5" angle grinder with a flap disk and Zip Wheel. Or better yet a plasma cutter!
paint pen or sharpieSmall welding clampHammerRazor knifeTorque wrench
140 amp or higher welder
All safety gear needed to preform the task
First thing remove the negative terminal from the battery, jack the truck up and remove the tires.
Then lay the BAMF plate on the cab mount and trace what you need to remove. Note I lake to remove less on the first cut then fine tune it with the flat disk. You can see the yellow mark on the left you will need to remove that plastic as well with the razor knife.
This is how it should look once cut and sanded down. 
Next you will want to tack only the back of the mount if you removed enough you will have a gap at the outside of it.
Now you take your hammer and tap the plate until it forms the cut. You don't have to get it perfect that's why you have the welding clamp. Clamp the cab mount and plate together until the gap is gone and tack in place.
Once tacked you can start welding it up. Now remember you are not out to win awards on weld appearance. Just stitch weld it staggering the welds so you don't over heat the rubber mount.
Now that it's all welded up you can now blend the welds as if they were never there. 
Once it's all blended prime and paint the mount inside and out to prevent rust.

The install is the same process as the Tacoma but you will be cutting the cap off the cab mount and re capping it.
