Well said and very true

I highly suggest you keep looking. You can find a good Z if you take your time and look.

Excellent work. Can't wait to see the final product!

There's a pic of the vin plate.

Checking in with 00903.

Thanks for your input. I am willing to try anything at this point. The car runs like a well oiled machine as long as you keep her below 70mph.

Excellent. Thanks for sharing!

Thanks all, I don't believe the problem is caused by the rims and tires since this is the second new set that I have replaced in two months (trying different syles of wheels.) I suspect that the u-joints or bushings might be a good place to start as suggested here. I had a mechanic at one of the shops that specializes in Zs tell me that the problem is caused by the drive shaft being too short from the factory and that the fix is to replace it with a 73 shaft. That seems a bit far fetched to me. I don't think the Z would have been such a success if they came from the factory with the type of vibration mine has.

Hello all, How common is it to experience high frequency vibs above 70mph in a 70z? The entire drive train has been rebuilt but I can't seem to get rid of the vibe.

Dunno... but looks like $h1t to me.

Do you still have your plate frames from them?

Yes I had the color matched from the spare tire well. The color it had before was not universal blue. I wanted to bring her back to her original color.

I just keep at it... color me anal...
