Replacement parts supports (specifically trans)
 

Hello all! New on the forum and have never owned a Mazda so try to cut me some slack if I am not sure what you're talking about but here is my question. What is part support like for the 323 GTX? I am asking this because I am looking into picking up a 88' 323 GTX for a Rallycross/Stage Rally platform and it had a ****ed tranny. What/where are my best sources to rebuild/replace the trans? (Live in socal). Also what is the support like in the aftermarket for these old 323s? Also again if I have commited any "forum crimes" and posted in the wrong area let me know and I will fix it. Thank you all for any help you can give.
