Sucks to be you
Sorry bud but I have been looking for the same shock for a year. After buying about 5 (bad) shocks off ebay I finally got one in good shape. You will probably have to have yours rebuilt. They show up on ebay all the time, but like I said be careful. These shocks are over 20yrs old. So they all have some use. If this one I have now goes, I will definately look at a rebuild. And there are no retrofitable shocks without major fab.
good luck bud
