[V8] V8 Spring Choices

[S_Matus]

I did some searching on the web and came across Intrax springs.  What has anyone any experienced with them?  See -

Is it true that the H&Rs are now out-of-production?  What other spring options are out there?
 
Is it true that the 4.2s have a larger diameter Anti-sway bar (Front or rear) than the 3.6s?  Is there a fitment difference by year or transmission?  Are there any after market Anti-sway bar options?
 
Thanks,

Scott.
