The plastic gears are also wicked easy to fix. A little dab of super glue on
the shaft for the tenths wheel has restored 2 of them for me.
IIRC I've promised to fix Dwight's, probably promised more than once, I ought
to actually do that.

Looks like a good plan, though I think I'd swap 6 and 7 - the vacuum system
also controls parts of the ACC system - it will be easier to determine what

Regarding #11 - a different cluster doesn't mean that it's odometer is
working either - the plastic gears slipping or breaking is a common issue.
Probably more effective to just fix yours. (The odometer died in the 300D
2.5T about 30 miles south of Wichita when I bought it from you).
