Correct fluid - Pentosin CHF 11S
As previously stated, steering box can be a weak point, later cars msut be running proper Pentosin CHF 11S in there. Earlier cars less picky. Known fragility to the steering, means a 3/8" Magnefine is a good idea. Wrong fluid soon rots the seals and at the cost of new racks, this is a P80 killer. Later car? Don't put ATF in there. Many do.

Tow bars & Strut braces on the C70
These cars are known to be a bit wobbly. You might not want such a thing on your rag-top, but word is, a tow bar stops a lot of the 'wobble' not just because of adding rigidity but the pendulum-effect damps down and hence slwos down, the sweet-spot at which the body will start to shake.

C70: 2001-2003 suffer from very fragile boxes
Flush now. Known issue, has same awful box as P2 cars in these years. A aux cooler is a must, and the only cure if you catch it in time. Left too long and a cooler or a flush likely won't cure it, to the crusher it goes. See previous points in this thread

3/8" Magnefine (and 1/2"?)
I like these in autos & steering for all. Buy two 3/8" , one for the your autobox and one for the steering. Fit when you flush. Exception: 1/2" fits the four speed,
