Gearbox identification

[moggy240]

Does anyone know the best way to work out which gearbox this is as I have lost the gearstick and I can't work out if it is 4 or 5 speed
I did take the speedo drive out and it was a blue cog.

I don't know what the physical differences are between 4 and 5 speed boxes but here's a few pics of my 5 speed (UK 1974 plate) and it looks the same as yours to me...
Hopefully they might help, maybe someone can identify any physical differences.

looks to be a 5 speed , blue cog would be 3.70 ratio diff , which from my memory would be from early 280zx dont thnk anything else we had came with a 3.70 , as we didnt have 510's ?
