have for sale or swap gearbox for 280zx. This is the long rear extension box. I bought this for an R30 not realizing I needed the short extension box. Seems to be in good order, have drained oil and taken the rear section off, apart from some slight gouging on reverse cog, looks to be ok but I am not a mechanic. Anybody has one or knows of where I could get a "short", would be most grateful.
