i have a set of koni coilovers on my a4, they where great until one blew out. I have had the set on for a long time now and don't have the original receipt of purchase. the only way to get them rebuilt is to take them off and sent them to a shop witch takes 2 to 3 weeks. I am wondering if anyone knows a way to get a single coilover because everywhere else sells them in package's. i cant have my car down for more then the weekend and i am trying to figure out some options. any suggestions?
