8. Reinstall the new billet door handle the same way you removed the stock handle. Test that they are working properly.

Our donor truck is a new Toyota Tundra 5.7L.  This thing is beautiful, with a huge cabin, leather seats, in-dash navigation...forget about it!  Too much to list! 

Our Toyota Tundra was missing something.  Could it be Westin Oval Tube Steps?
 

This is the underside of the Toyota's body.  Just underneath the side of the truck there are a series of mounting holes.  In our Tundra's case, these mounting holes had bolts in them.  The mounting holes on your truck or SUV may be empty. 

Now we attach Westin's mounting brackets to the holes in the underside of the truck.  We are using the bolts that were supplied by Westin. 

Tighten the bolts down to attach the brackets.  Leave them slightly loose so you can align your step bar before tightening everything down.
 

Here are the mounting brackets all lined up and shiny looking.  You'll also notice that we have the truck up on a hydralic lift for the installation of these tube steps.  Westin makes the installation so simple, you could (and many people do) install these while lying in your driveway.

Now we can see the channel on the underside of the tube steps.  Those four bolts sticking down are part of the bracket that fits into this channel.  Obviously, these four bolts also stick down into the mounting brackets that we just bolted to the body of our donor Tundra.

Using Westin's supplied hardware, we tighten down these brackets, securing the tube step to the black mounting brackets.
 

A couple of strong twists on the ratchet make light work of these nuts.
 

Now you just need to tighten down the brackets on the body of your truck.  Of course, the instructions give a specific ft-lb to tighten the bolts down to, but we just went with the ol' grip it and rip it approach.

The finished product looks killer on this truck.

Here's one more shot of the truck, just to make you jealous.
