The D90 requires a lens with an AI mount to prevent damaging the body. Nikon introduced the AI mount around 1978 so your 1964 lens will require machining the mount to the AI standard. The cost is about $35 plus shipping and is performed by a few shops on the internet.
One source I have used is john White. Check out his site here:
After the lens is converted to the AI standard it will mount on the D90 but you won't be able to use the D90's metering. You will need to use an external light meter and use the lens in the manual mode. However the lens will still maintain it's auto stop down feature.
edit: What can get damaged on the body is the little switch located just outside the chrome lens mount at about the 7:30 position looking at the front of the camera body.

Just a note, you can use an external light meter but I just use the Histogram. It is easy to adjust from a "off the top of your head guesstimate". Sunny 16 works if you are familiar with it as a starting point. Since you Shot "old School" your feel for initial exposure will be quite close I am sure. You can "dial In" your exposure easily referring to the Histogram. Also the D90 focus led works as well. Not having a Fresnel or split image screen it is an excellent confirmation of your focus with Ai lens. Good luck. JB
