Eunos roadster diff

[dean211277]

Hi.
Having read the post by Talon about the uncertainty for his workshop I think I need to order one of his differential covers.
On Talons website I have to choose whether I have a short/small diff or a long/ large diff, does anyone know how I can tell which I have?
If it helps my donor is an important 1.6 eunos roadster with I believe a V.L.S.D
Cheers Dean
