I believe it is near impossible due to the computers involved, but idk, nothing is impossible in my book

Check the parts on line. The E350 vs E500 if the parts are the same they should bolt up.

Now the computer. It must be tricked into believing it has the correct shock. If the shock is a coil with magnetic fluid and varing the voltage/current to the coil changes the fluid flow you have a shot. This means the current to the coil would be the trigger probably to the computer function. If you could use a wire wound resistor as a replacement for the circuit it might be possible to determine a value that would let the computer "think" the signal was getting to a shock when in actually it would be a resistor. So an old shock to evaluate might be helpful in this case. However if it is pizoelectric or a switching/solid state device inside it might be more difficult

ON THE KISS theory I would suspect the coil which might make it possible to work around the computer. I have already determined (IF I remember correctly) this on the C5 corvette and a 25 watt 10 ohm wire wound resistor works on the C5 and the computer doesn't know any difference.

ON the MB however I don't have enough information to say it can work electircally ,, but in theory it should.

So if your parts match for the E350 to the E500 you have a shot. Good luck.

Probably doesn't want to worry about the SBC pump or airmatic shocks breaking in the near future. Since those parts are fairly costly to replace without a warranty.

Probably not worth the expense, hassle and time. Airmatic shocks can now be bought refurbished with lifetime warranty for a fraction of what the dealer charges, and some people have suggested that they can be replaced easy as a diy project.

You are correct on the shocks but the rear air springs are a different topic. They are much more complex than just changing a shock. If you change the air spring the shocks will have to go also.
