it turns out I bought the wrong oil pan for my rx3. I bought from somebody on this website. It has never been used, but I do know it is an oil pan for a full-chassis or full race setup. It is neither first gen or any other gens. I am asking what I paid $$$ 200

 

Moroso only makes two kinds of oilpans for the rotary. One is for the 3rd gens and which would be also for the "full chassis" cars. And sounds like the one you have. And the other is for any 13b using a 1st gen front cover where the engine mounts are on the front cover and the sump is towards the front, I have one of these on my car. If I were you just get a oil pan from a gslse you can get those new from Racing Beat or Mazdatrix for like $80 bucks.
