1992 Porsche Struts
 

I have ben informed that Porsche has stoped making rear Struts/guide arms for my 911. The Porsche part # for these struts is 964-331-060-08. If anyone has any ideas or suggestions as to what/where I can find out how to replace or repair these. I really only need the bushing/bearing, but they are not available seperately.
Thanks
