I need help in finding the best supplier to match the seats in my 77 280z. As you can see in the top picture the covers I have are way off. I need something like the lower picture. 

The actual color you are looking for is Ginger.  You are going to have to look at samples from different vendors to even come close.  That being said, I found these on Ebay.  Looks close but they call it Burnt Orange.  A lot depends on how accurate the color is on the photo and your monitor.  Good Luck!
