standard cirrus stuff wanted

Hey everyone,
I'm looking to improve my ground handling gear for a standard cirrus.
Does anybody have a really nice tail dolly, I could buy a new one from wings and wheels, but a very nice used one would be as good.
Also, I'm working on a disk brake mod that might or might not be approvable,
and would be interested in a control stick, just the upper part from the retaining bolt up including lever and grip.
a seat pan insert, the one for "stepping" a parachute also.

I might be interested in whatever you have, let me know.
