They're called "cylindrical isolators", Grainger lists them in the big catalog, once you have the 
part number you can buy the identical parts brand new on eBay for 1/3rd of Grainger's price, 
shipping paid and no tax.

Dumb design - they're supposed to be loaded in compression, Audi loads them in shear (so does 
Cessna), and they fail quickly.

You may have to cut/trim the studs, but that's trivial and well worth your time.
