I have a 78 TA, that I just competed a battle with my braking system hydraulics that was very tedious, just today I discovered a puddle on my garage floor, and was thinking OH NO, not again, here it is not my brakes at all, it is leaking somewhere at my steering gearbox, power steering fluid, cant seem to locate where though, anyone have any experience with this, looks like a job to replace it, where do these leak from, cant seem to find exactly where except maybe the inlet shaft? And how exactly does the steering shaft attach to this unit, it looks like a clamp, but has this wierd connection just before it, my chiltons manual is sort vague on this connection.
