Last things first: trans linkage is a pretty easy job. If you have ramps to work with, I suggest jacking the car up on the left side and putting a ramp under each left side wheel. Access is much better this way.
The linkage hangs along the left side of the transmission. The adjustable rod is clipped to the bottom of the shift lever with a snap clip. They're similar to the clips in the doors that hold the window regulator together. Anyway, snap off the clip, push out the old bushing and put it back together with the new ones. You may want to spray the thing with brake cleaner before you start since it's probably all filthy under there. Also, once the new ones are in, I'd use a little lithium grease on the pivot points to keep it moving easily.

The K number identifies a sedan or wagon speedometer. The 92 must be a sedan. The wagon gets larger tires, therefore generating fewer counts per mile: hence the 9800 on the wagon vs. the 10042 on the sedan. In theory, the number indicates counts per mile or pulses of the pickup in the rear axle. Actual number varies slightly with actual tire diameter. If you replace a speedometer, you need to match up the number. IF you ever break the odometer gear, one from either type of speedometer may be used to replace it.

Glad the MAACO paint job worked out. Hopefully the prep work was satisfactory. Good that they warrant it for 4 years, that's a pretty decent guarantee. Hope you never need to use that guarantee!
