I researched this and the hydraulic unit does not produce the force you will need for the spring. At least the 123 spring.
The internal unit, you can't get it into the interior of the spring. I have one and you can't get it in the spring opening at the top. The 123 has a plate at the bottom so that way is also out.

Consider buying or renting the SIR TOOL of the Klann tool. I know its expensive but after doing the 123 suspension, both front and rear, I would not use any other kind of spring compressor on the springs. I did a 65 Mustang with the internal type of compressor. It was fine. the springs are not that tall and rather weak. The Mercedes springs are quite tall and VERY strong.

Performance Products rents the Sir Tool and do a search on the Klann unit. Some one on the forum is trying to do a Group purchase to get the price down
