Crown Vic P71 front and rear suspension replacement suggestions…

I recently purchased a 2003 P71 for $2800.00 with 115,000 miles on it which I personally think was a steal. But the person who sold it to me back when I got it in December, told me that I would probably need to get the suspension replaced eventually. So my question is what a where do you guys suggest which route I take. I see this set on Amazon ( front and rear ) with sway bars but in the notes it says Taxi Package… Can I use these on a police package??? Sorry I’m pretty new here… haven’t over a Vic since my ‘93 way back in 2005
