Display Housing Replacement Compatibiliy options

HERE they sell LCD housing for various machines. However according to i fixit the 2008-2009 has a different housing from 2010 and 2011.. But at this website they say it is compatible with

MacBook Pro 15" 1.83/2.0/2.16GHz Core Duo

MacBook Pro 15" 2.0/2.16GHz Core 2 Duo

MacBook Pro 15" 2.2/2.4/2.6GHz Core 2 Duo (Santa Rosa)

MacBook Pro 15" 2.4/2.5/2.6GHz Core 2 Duo (Penryn)

However they go on to explain the older versions had 3 screws for the old isight and then changed to 1 for a newer Isight.. I am trying to figure out if i too can use this for mine, or if id have to also buy a new isight.... I am trying to replace my entire housing as it had a few accidents.. Ive already found new topcase with a bad keyboard that i am going to switch out.. thanks to i fixit showing the secrets behind what apple calls one part at 214 dollars got the top case for 50 of ebay.

SO my question is WOuld one of these work to replace mine ... would I just need to buy an new I sight too?

please share
