Folks, I don't mean to burst anyone's bubble but original sound deadener is still available from Nissan by the sheet. Just need a cooperative Nissan parts guy/gal.

Would you happen to have a part number for that?

Nissan used sound deadener of 2 thicknesses. The thickest was used in the cargo area. The 2 part #s are G5930-89902 and G5930-89904. I'm sorry but I don't remember which is which but they aren't very expensive.

 G5930-89902 is discontinued.  This one brings up a diagram at this site which is not a 240Z, but still shows it is available: G5930-89904.  It may or may not be.  I've ordered items from that site that have a price, but turn out not to be available any longer.

Many thanks for the heads-up on this. I gave up and had the original thick sound deadener at the firewall cleaned and deodorized at a fire restoration company. Then I re-installed it.

I just saw the other day that Eastwood is selling it in sheets. Just in the past 5 days or so.

Unfortunately it's too late for my car.

G5930-89902 is discontinued.  And though I was able to buy G5930-89904, it appears to be about .060" in thickness, and what I took out of my 1971 from the tunnel (floor "mat" was already gone) is about .090".  Package shelf appears to be about .090" as well.  It would be nice to confirm original thickness of the pieces for the floor and the tunnel, as well as the rear deck, for US cars that had them. For the record, I measure my 6/1971 tunnel pieces at about .090".  I will measure the package shelf piece and edit this post to include that information.

Edit - 5/9/2020:

The original package shelf sound deadening material is also about .090" (Same as tunnel).  I bought a pack of the Wurth sound deadening mat and unfortunately they have improved the product.  It now has cloth on the upper surface which is white/silver to my eye.  It no longer looks black like the original Datsun stuff.
