You will also need to make a spreader bar, the tires MUST be pre-loaded
outward or the toe will be incorrect while driving. This will eat
tires and make it drive badly. Only a small error causes big trouble.
It will be much cheaper and easier to get it close and drive it to a
good alignment shop that knows how to do Mercedes -- they are NOT like
american cars. There is quite a bit of caster (8 degrees or so), so
toe is critical and should be set on a computerized machine, not by
measuring the centerline distance. I doubt if you will get close
enough to satisfy you.
My tire shop charges $35 for a two wheel alignment -- kinda stupid for
me to attempt it. I get the new tie rods as close to the old ones in
length as possible, adjust so that it doesn't pull either way, and go
to the shop.
