Has anyone used these???

Seems way over priced.
For example;
http://www.carid.com/1985-ferrari-308-control-arm-bushings-hardware/

Also sponsors here sell kits for less.
T.Rutlands advertises $390 for complete front kits

Also more complete kits from here;

The vendor is misterfiat - I believe they have a reputation here for being overpriced. I have bought an item of two from them when I couldn't find it anywhere else, but otherwise I have not bought from them as a first choice.

Another vendor that sells a lot on eBay is maseratisource, and their prices are often very good, including on suspension bushings.

 

+1 for Maseratisource for all suspension bushings, tie rods, ball joints make an offer below the BIN

 

I got ball joints from Maserati Source. Cheapest price shipped right away.
Would look to them next time I need parts.
