Through several years I have been posting a piece on my experience when dealing with front-end Hassler shocks. Because the results of my tinkering worked out petty well, here is my piece again.

Gene, that's great, thanks for the links. I was just about to do some learnin' on those. I found a set of the double kind in the back of my car when I bought it, but have yet to install them.

I see that I will have to remove the front perches, and exchange them left for right. Boy, sounds like fun.

Hasslers are named correctly.They are a hassle.
Steve Jeff has made a apparatus to remove the perchs that looks to me like it would work wonders.You may want to get up with him for the measurements and specs.
