That's the same thing the honda guys use but they use a phantom grip one. Years ago i ordered a SR20 tranny from a place in Cali. and they sent me a 50 series and i sent it back because it was wrong . A few years after I found out with a little fabrication it could have worked . That could have saved me at least 10 of the B13 trannies i went through, now i can't even find one . I also have a B14 race car that has one in it but it has a welded diff so i can't put it in my B13 for street use.
