Thanks!
Unfortunately, not for 1990. There are factory service manuals avaialble for 1994 and later Q45 at
http://www.nissan-techinfo.com/infiniti/ for a one day suscription of $20. The specifications from these will be sufficient for your year, although the front shocks require a slightly different mounting bolt size on the later (1994-1996) G50. Also, all of the invaluable Technical Service Bulletins are available also, including ones applicable to your year.
Be sure to order all the rubber from Joe at
http://www.everythinginfiniti.com , one of our sponsors and our man man. He can get the Tokico Blues for you also. Anything you don't use, can be returned fro credit if unopened. Be sure to include the upper links as you will most likely need them. If is fine to just order the tension rod bearing insert and press them into the old eyes instead of the whole assembly.
Doing the suspension is fairly straight forward, but be sure you get a good four wheel alignment afterwards. Read the posts by Q45tech on the importance of the absolute correct settings with the driver in the car. Sloppy or near-enough work will not be sufficient for long term performance.
The rewards are great.
