Hey there, I noticed your post & i think i may be able to help you.
I had a T-18 wreck in my back yard & I kept the diff plus the Tail shaft you need.
I'm guessing this will be for AE86 sprinter diff conversion??
Any way I'm in Adelaide, & i can arrange freight 4 you if your interested
please let me know if your interested.
