9 bolt axle install, need help
Swapped from an 87 GTA 10-bolt drum to an 89 9-bolt disc.
I got the axle in but what gear oil is recommended for 9 bolts?
What do I need to get the emergancy brake lines connected and working properly?
Do I need a longer cable from front to back on the left side?

Use 80W90 gear oil and a bottle of Ford limited slip oil additive. You can use the GM additive, but you might need 2 bottles to get it to stop popping when you turn a sharp corner.
