Sheesh, all that work to convert to manual controls. To convert, you will likely need to remove the dash anyway so personally I don't understand why go to a considerably bigger headache. I know the manual system sounds simpler but a conversion certainly is more than most people realize.

I refurbish the ACC system on my W126 with new pods and really enjoy how well it works. (I know the W126 is easier than the W123.) I did the entire system in a couple of afternoons.

Just some thoughts to take in consideration.
