Re: disc brake conversion
Yes, you will have to get disc spindles.

Re: disc brake conversion
As far as I know the control arms are the same. But you'll need to change the ball joints and either change the steering center link and use the 71-72 inner and outer tie rods. Or I think you can get an adapter to keep the stock center link and inner tie rods. The 69-70 and 71-72 tie rods have different thread sizes. (I can't remember what they are though.)
