If you have any friends that have a welder and a few tools you can make one for about 10-15 dollars US.... you need a piece of about 19mm thickness all thread rod and about 50 centimeters long, 3 nuts one washer and 2 plates. if you are interested I will draw the plans and take pictures of what I have built.. works perfectly on any mercedes that has a hole in the top spring perch...
