I have a set of burnt orange leather seats, PM me if your interested.

 

Here is an installation guide to replacing the seat covers, maybe it would help you: http://www.leatherseats.com/350Z_installation_guide.asp

 

This is of great help to me, thank you very much.

With the design of the seat supports, I am now I am now wondering where the noise is coming from again, unless it's where they attach to the seat frame.

I'll have to look and see.

Thanx again

 

You might need to tighten the 4 bolts holding the seat pan to the seat frame.
