I've got a mint low mileage 6 speed manual transmission from a newer 350z.
It is in fact the newer/stronger redesigned transmission. Less than 50k on it, came out of a crashed car. Still in perfect working condition.
Great transmissions overall, I think they even make a bell housing to mate it to SR20/KA24s and most engines
Best way to contact me would be text or email
