Hey guys, hope this is the right category for this listing. I have an 89 crx si with a dohc zc swap with the si tranny. 4th grinds a little bit along with others if I drive it hard. I bought some synchromesh to put in but it says that it's only made for certain GM trannys. I would assume that I could use it in mine, but I just wanted to ask someone who knows just to make sure. Thanks.
