03 Deville DTS Newbie

Hi guys! I finally purchased a caddy with a northstar engine. My friend told me the 00's are better than the previous model years. I have two questions: 1- I need some new shocks in the back, and I found some that were over 450 dollars, and some for the DHS (which I don't the acronym for) for a lot cheaper. I was wondering if I could use the ones for the dhs on my dts? Whats the difference? and 2- I need to replace the plenum, can someone tell me how expensive that is?

Thanks in advance

Phillip

The DHS has a softer suspension than The DTS. I suspect that is the difference.

The plenum is not expensive. Do a search for it. SUB has posted many times with diagrams regarding it.

Plenum, $40 +/-, dealer only. #12555840. 3 long plenum bolts through the throttlebody. Manifold bolts are 89 in/lb, 7 ft/lb. Not too tight.......

I'm easy - waiting for dental appointment time - yuk.
