SC trailing arms on early car?

[Scott Clarke]

Is it possible to install SC trailing arms on a '70? I know that the sway bar mount is different, but is it just a mater of replacing the hardware, or is the arm casting itself different? Also, I have read conflicting posts concerning the stub axle compatability. Anyone tried this? I know that it would be easier to use arms from '74-'77.
Thanks n avdance,

I have late 80's Carrera arms on my '74, they are a straight bolt on, so if '74 arms fit a '70, then it folows that SC/Carrera will fit too.

The pre 74 arms are fabricated steel, the later ones are cast aluminum.

Did you swap out the sway bar mounts?

These were fitted on the car when I bought it, but I believe you would have to sort something out for you car

Is your drop link mount (on the arm) the early ball type, or the later bolt type?

Bolt

Thanks for yur help. One last question: are you using an early type sway bar? I'm wondering if I can mix sway bar components (use my existing bar, and modify the way in which it is attached to the trailing arms).

I have a standard 74 bar

Nick; keep in mind that both your car and the SC have 915 gear boxes. A '70 will have a 911. The reason that this might be an issue is that the half-shafts are different, as well as the stub axles. When I put some '76 arms on my car, I need to replace the stub axles, half-shafts and the output flanges on the gearbox. I basically had to use 915 output flanges and have about 1 mm machined off of the diameter of the bearing surface so that they would fit. The other change is in the shock mounting which can cause the shock body to have clearence problems with the heat exchangers or the tube in the body in which their mounted. Nothing that couldn't be solved with a bigger hammer!
