The green Defi gauges you are looking for are called the "LINK-Meter". Check here: http://www.defi-shop.com/product/meter/meter_top.html
Unfortunately Defi does not manufacture any sort of bezel that can be placed around OEM gauge cluster. They only make a triple meter hood that goes where your clock is, and they also offer swivel cups that can be attached virutally anywhere via double-sided tape.
Since the LINK gauges are 52mm you should be able to pick up an Autometer gauge bezel that fits around your steering column. It'll look alot more flush and OEM-like, compared to the Defi swivel cups. Here's a link for the autometer bezel:
