Steering ratio

[npca-hombrey]

I have just acquired what I think is a 72 Patrol.  Its had a hard life.  I want a good off road vehicle. I have just got it mobile and it goes great aside from saggy springs and no back shocks!  These are on the list however, the steering takes many turns lock to lock.  Anyone know a steering conversion that will improve this?  Also want to add a disc brake front end.  Are there any disc set ups that will bolt in from a later model?
