2002 Hard S Shocks VS Bilstein B8
One of the front Bilstein Shocks on my car is blown, I only figured this out til I had taken the entire car apart and was putting together a set of DIY Bilsteins. Had to pick up an overpriced Monroe strut to get back home, I can't find any used Hard-S Bilsteins locally, and I can't figure out where to order any used ones online. I have been searching the internet to figure out what part to order, my blown shock shows a part number of NO6734700, which is close to SixShooters pic of his Hard-S Bilsteins P/N of NC1234700, which is also a picture of a front Hard-S Bilstein, off of a 2000 Miata.
Is a Bilstein B8 the same shock as the Hard-S? I know that mazda changed the Hard-S Spring rate between the NB1 and NB2, but did they also change the Hard-S Shock Valving as well as the part number?
UPDATE - Found some Info, the part numbers for the 99-00 and the 01-02 bilsteins are different, shown in this archived forum post
Not sure if they are actually valved differently

A B6 is as close as you'll get OTS new to a Hard-S. The B6 & B8 have the same body length and are valved the same, the difference is the B8 has about 1" less stroke / droop travel (they'll have the same bump travel once loaded on the same spring).
There's not much documented about any valving difference between the two. Despite them being different part numbers, my money is on them having the same valving.

New (to me) Bilsteins are in, they are the same part number as my 2002, these came off a 2004. For future reference, Bilsteins on NB1s have a part number of NC 1234 700D, while NB2 Bilsteins have a part number of NO 6734 700. They both have the same valving and shock body, barring the part number. It would have cost me 239$ for a new NB2 Bilstein from my local dealer, so I would recommend buying used.
Both of them rebound the same, and are in very nice condition for the price I bought them for. Will put them both on tomorrow.
