Does anyone know where I can purchase strut inserts for my 72 240z. the local shops say they are discontinued.

Try shox.com. I bought 4 KYB strut inserts w/ boots for my 1973 Z for $242 delivered to my door in 3 days. They weren't too hard to install...check out the "search" feature for help. Cheers, Mike

Lots of places still have them or can get them. The major brands that are still available are KYB, Tokico (both normal and adjustable versions), Monroe Sens-a-trac, and Koni. All are gas-filled except the Konis. The KYBs and Tokicos can be ordered from MSA or Black Dragon, among others. If KYBs are what you decide on, you can get them from this guy on eBay for $140 delivered. He almost always has a set offered.

One thing to note - most people notice that gas struts with factory springs tends to raise the ride height some.

Thanks alot for your help I will check this stuff out.

I just installed the KYB GR-2 strut inserts on my 73. I ordered them from jdmwerks on ebay for $152 after shipping and CA tax, best price I found and quick shipping.

I am very pleased with the ride difference. It does not feel soft or floaty anymore and they give plenty of support for spirited street driving while still providing a comfortable ride.

Ride height was a concern for me since I am using the stock springs and the 73Z started out at 8 1/2" ground clearance at the rocker panels (185/70-14 tires). I cut 1 1/2 coils off each of the stock springs when I installed the shocks and it now sits at 7 1/2" clearance at the rocker panels. I have read warnings against cutting the stock springs but I figured I could not live with the stock ride height (or higher) and it would give me an excuse to buy a set of Eibach springs if I was not happy with the result. As it worked out the cut springs are working great and the combo gives just the ride firmness I was looking for.

As a side note the car has much less body roll and the steering response is much tighter with this shock/sping setup combined with urithane bushings on the stock sway bar.

It now drives like a sports car rather than just looking like one.
