So I set aside today to replace all of my front end bushings on my '72 240 w/ a set from Energy Suspension.Lo and behold, what do I find? Some interesting things. For one I find that a previous owner put in the "Performance T/C rod kit" You know the one w/ a metal cup and plastic fitting instead of a bushing on the front side. He also left the original rubber bushing in the back. Kinda defeats the purpose doesn't it? Also I've been having some tire wear problems as well, the driver's side front has severe wear on the outside edge only. Well, come to find out that the front control arm bushings were replaced w/ an adjustable type. I've never heard of these before, have you? Anyway the bushings on it were wasted, so I just took them out, Apparently they were way out of adjustment anyway. The question is where did these come from? It seems to me that using these would be alot easier than installing camder plates. Problem is the bushings on them are shot. Any body interested in them? I'll let 'em go for cheap. Well the front end is much better now and the shimmy is almost gone. I'm thinking ball joints and inner tie rod ends next. Any body know where I can get a set of inner tie rod ends for a '72 240?

HI CaliforniaZ.
Yes, you can purchase the inner tie-rods from your Nissan dealer. The only choice for critical hardware for your baby. later, shane-

As for putting adjustable bushings rather than camber plates, here are some pros and cons.

Pros:
Bushings are easier to install. may give you up to 2º negative camber depending on how low your car is. (compared to up to 4º negative with camber plates)

Cons:
When you adjust the camber down at that end instead of up top (camber plates) the allignment is affected because you are moving the controll arm and the tie rods are connected to them. Not really a big deal if you plan on having an allignment shop do it and leave it. But if you're going to change set ups frequently (street/race) then it becomes a big pain. Camber plates won't move the allignment so you can change it at will.

Hope this helps.

Probably what the control arm and T/C bushings are G-Machine. They may still be availabe at Nismo Autosport or Mortorsport Auto or Victoria British, but G-Machine may out of business,replacement parts may not be available.Yes,The rubber the bushing is intended
to be used with the T/C parts 240 Al

Actually they sound like the old Kontrolle parts, and it doesn't matter if you change camber at the bottom or top, it still changes your alignment. The other downside to the aluminum/delrin control arm bushings was that they only allowed for up and down movement of the control arm, no twist. Twist is caused by the connection to, and pivot with, the T/C rod. So these type bushing either eventually crack the control arm of wear themselves out. A true spherical bearing or poly bushing is much better for this application.

Thanks Guys

All of the info was great. I had not previously heard of these parts but after I saw your responses I looked a little closer at the Vic Brit catalog and found them in there. These parts had probably been on this car for about 10yrs, so it was time to replace anyway. After I finished the front end yesterday w/ the Enerhy Suspension bushings, the front end is much tighter, the shimmy is almost gone and The steering wheel is now off center when going straight. So these things were definitely messing up my alignment.
