I have the autozone "special" that is whats used in the 65 mustang.
1 They are very difficult to use in the Mercedes springs.
2 They are very dangerous to use in the Mercedes spring.
The force of the Mercedes spring is quite high. As an Airline Pilot I won't compromise safety for a cheap fix. Its my life and livelyhood.
Had a Mercedes service technition tell me a story about a guy at a dealership he worked at. He was taking a spring off a 560SEL. the unit dropped, released, flew up and hit the car. it knocked the car off the lift on to the car next to it.
Thats a lot of force.
