I'm sure you have all seen the the links below but I haven't heard anyone mention them so hear you go. Some interesting facts. I can't make heads or tails of any of this stuff but it seems the h190 is the same as a datsun roadster, 200sx, and a 510 wagon which is not the same as a 1200 but i know you can swap the rearends fairly easly. My friends 1200 has a wagon rear end. I also know that LSD is possible in these cars depending on the type of h190 you have. Now feel free to bash me if you guys knew all of this. It is my first post after all
