I have a complete rear end from a 1.8 - diff, subframe, wishbones, driveshafts, uprights, calipers, shockers.
How do I tell whether it was from an NA or an NB?
I understand that the diff has a different uni mount - how do they each look?
Would the brake disc size indicate this?

Thanks - Gavin Eakins,

NA has flat lower spring perches, NB spring perches are the same shape as the spring if that makes sense.

NA sway bars have rubber bushes on the wishbones, NB's have ball joints.

Thats 2 differences for you

This pic from under my NB May help you...than again it may not -

The sway-bar brackets on the wishbones have two tabs on NAs, one tab on NBs (to account for the aforementioned different sway bar links).

Early 1.8s had separate stub shafts on the diff, later (post ~96 used single piece half shafts)
