The fitment of that kit looks decent IMO. Not perfect, but close enough. I would drive it.
You can purchase kits from almost anywhere (Ebay, vendors galore, etc.).
Katzkin is a brand that I have heard people use a lot. I have heard the leather is medium quality at a medium price. You can always get better, but it is more expensive.
I have seen a lot of people order from a place called importsxtreme.com or maybe extreme.com with an e, but anwyay, this one guy visits a forum called
www.twinturbo.net and his name is aspendog on there. I guess he makes the kits. That particular forum is for 90+ Z32 300ZX, and 300ZX Twinturbo (specializing in). He has sold kits to a lot of members on that site. I wonder if he could somehow make them for Typhoons.
