I finally got to the suspension and the upper control arm bushings on both sides are bad .the drivers side the rubber is completely gone . How do I tackle this ? What do I need to know about removing the control arms safely . Going to replace what ever needs replacing .
To remove the UCA's you'll need to jack the car up, loosen the torsion bar adjusting bolt so that there's no load on the suspension, separate the UCA from the spindle at the ball joint, and remove the camber bolts. At minimum, anyway.
I would suggest deciding on what you're going to do with the suspension and brakes FIRST though. If the UCA bushings are worn out to the point of being completely gone, there's a chance you've damaged the UCA's. Even if you haven't, that amount of wear would suggest to me that every single bushing in the front suspension will need to be replaced as well.
If you're planning on converting to the later 73+ BBP brakes, you'll need new UCA's, spindles, brakes, bearings, bushings etc. So, your best bet will be to make that conversion before you start replacing the old bushings. Otherwise you'll just end up doing it all again later.
