[urq] early suspensions

[Fluhr]

Martin provided a nice bit of info about using the RR ball joints.  I wish
I had known that earlier.

I did a suspension overhaul on my Urq, which uses the early ball joints.
Because of parts availability and cost, and the likely future of both, I
went with a conversion to a CQ/90q20v suspension.  I have a few non-reversible
changes from stock to make it easier for the Urq, but overall it can work and
updates the car to a 15 year newer suspension.  I expect that gives us at
least another decade grace period before Audi drops those parts, as
well.

I expect that as the future goes on, more cars will have to update to
newer, more available parts to stay on the road.  In that respect, we
are fortunate that enough of the Audi stable is similar so that we
can cannibalize parts.
