Hey guys, Been a few years since I've owned a Datsun(coming from a 280z) Looking to get another one. I am pretty much set on finding a 510 but I am curious about the differences in models on the 610. I've googled everywhere and can't seem to find the answer. So whats the difference between a 610, and C110 and a 240K? Besides being JDM and AUS versions, are these all the same car outside of the engine? Can the parts be interchanged? The reason I ask is curious about taking a 610 and converting it to a 240K. Thanks!
