I have a 1978 280z. I'm currently trying to change from rubber bushings to urethane bushings. I am working on this car trying to learn how to do things on my own. I can't seam to find any how to sites that will answer my questions. I bought the bushing kit from motor sport magazine, but it didn't come with any instructions. So if anybody can offer some kind of guide that would be great for a new enthusiast.

Try and be a little more specific.

What bushings do you want to replace, what workshop facilities do you have access to, etc.

The project you describe is not difficult, I just need a few more details to help you.

Polyurethane bushings are often referred to as "squeakathane" here in Oz, but I personally haven't got any complaints about their performance or noise:devious:

It appears that you have inadvertantly posted this topic twice, twice:classic:

it's not too difficult, but as nissanman said, post specifics on which bushings you need help with
