I am new to this website other than a question several years ago. I have a 74 260z (I believe early model) that has been a project for a couple years now. A complete 77 model rear suspension was installed in the car including trailing arms, R200, mustache bar, etc. I used the original 260z springs, but the car sets so high that the universal joints bind and will not let the wheels turn.
I cut off two coils from the springs, and used 240z isolators at the top, but the car only went down an inch....from 6.5" to 5.5", measured from top of tire to lip of fender. By comparison, there are only 3.5" of space at the front fender/wheel.
The drivetrain is installed and I would appreciate anyone making comment who may have answers to help me move forward with this project.
