If you decide to go the piecemeal route it won't take you very long before you realize you should have just went to a Z specific vendor. Ross at Modern M has already gone through all of the trouble of matching parts that work on a Z. His stuff just plain works. I also started out thinking I was going to save a few pennies by "shopping around" but in the end I went to Ross and am very glad I did. He helped be sort out my needs and eveeything went together right the first time. I am using 280 strut tubes on my 240Zt for no other reason than I had them laying around. I shortened them, installed a set of Tokico's, and adjusted everything in no time at all. I know this sounds like a commercial for Modern Motorsports but I had to throw kudo's where it's deserved.
