I used a "coolant Recovery" bottle from Pep Boys. Comes with fire-wall bracket and hose (fits where stock pressure bottle goes). Insure your radiator cap is intended for use with a recovery system. The proper cap has two internal valves; one lets coolant escape as it expands with heat, then the other lets coolant from the recovery bottle return to the radiator as it cools (causing a vacuum in the system).

No pix but I used a generic $15 bottle from summit...

Put the hose from the radiator neck to the bottom with the valve open, and put another piece of hose off the top for the overflow.

I used a doubled-up piece of plumbers tape (steel strap w/ holes) and mounted mine in place of the factory bottle "shelf" using one of it's bolt holes
