Yep the 280zx box can have different rations depending on early or late, late box is close ratio with an high geared 5th.
They use brass type Borg Warner sysncros which are easier to get replacements for rather than the porshe type steel used in the S30 boxes. The late 280zx has some minor casing differences longer "ears" on shift mount and only a single exhaust mount point at the rear. I fitted one to my 2602+2 no problem and has been quite a bit better.
The early 280zx is almost the same as a 260z box, but with the differnt syncros.
Should have one in my lockup gathering dust. Ill have to check though as it may be at Terry's. no reasonable offer refused. Your local as well so no postage costs.
