Can I change just the bushing or do I have to get the whole thing.

 

The upper control arm anchor bolt bushings can be easily replaced with a complete unit or take a look at www.specprod.com and you will find that they offer eccentric bushings that go in the stock housings (you may have to call them for this one). BTW: the eccentric type is the only one allowed for Improved Touring in the front of a Honda Civic/CRX.
