Things that aren't that fun to get to,repair, etc.
Currently working on a power steering box that I botched and it got me thinking.

1. Dash removal
2. Rear window regulators
3. proportioning valve with the engine in.
4. steering box with the engine in.
5. headliner

Let's see your lists.

Is the dash that bad? I'm pretty sure i'll be removing my dash when I go to rewire my car and I figure it can't be as bad as any late model car i've done.
