Interchangeability of 5th and 6th gen springs? Options

[GotToyota]

Will 5th gen springs work on a 6th gen? Long story short, I can get a good deal on some ground controls that this guy had on his 5th gen, and they should be the same right? On most sites I see for springs, it always says 90-99.

In a related question, does anyone know if shocks from a 5th generation will work on a 6th generation? Also, are there any other parts that can be used interchangeably between the two generations? Here in Canada, 5th generations are fairly cheap and common whereas 6th generation are very rare and generally expensive. Thanks. Any light shed on this would be greatly appreciated.
