I'm replacing the dash on my '83 300CD. What else should I do while it's out?

So far I've got planned:

New radio (already bought, waiting on Crutchfield harness)
New speakers + wires (leaving factory wires; 3.5" mounted from underneath)
New center vacuum pod (just replaced defrost pod)
Clean/flush A/C evaporator
Probably need new A/C temp sensor foam tube
Possibly replace ignition switch (current drilled out switch is held in place by PO installed hose clamp)
Paint dash needles
Maybe replace instrument bulbs with white LEDs -- any experience?


I've recently R&R'd the hood cable and lubed the speedo cable & speedo with Boeing T-9 spray lube and have almost no jumping.

Are there any other cables, hoses, grommets etc that are easier to replace with the dash out?

Should I lube or replace the blower motor bushings or contacts?

The car's been in Texas since '93 and is about as rust free as you can get. I haven't noticed any leaks up front. Anything else to look for while it's opened up?
