Actually, I just had a thought about these.
The whole diff was originally bought from JustJap (importing company) so the diff could be from a Jap AE86. It has a drum rear end, and the centre was an LSD factory centre.
Has Swaybar mounts on the housing.
I am not sure on prices for these, I thought $150 was sort of fair, but maybe I am pushing it a bit.
Make offers on them.
