I'm looking through the PET to establish what I need to order, what things need to be plated, and what things need paint/powerdercoat.

The engine section lists part numbers for engine bay stickers:
E 022 100 173 - ignition point (all models)
E 039 100 175 - valve clearances (2.0)
E 022 100 173 B - sticker (1.8)
E 022 100 173 C - sticker (1.8 Cal)

Case Perimeter Bolts:
M 8 X 45 X 22 - Top, at bellhousing
M 8 X 95 - Top, one forward from bellhousing
M 8 X 65 - Top, two forward from bellhousing
M 8 X 88 - Top, three forward from bellhousing
M 8 X 113 - Front, above crank
M 8 X 42 - Rear, under crank inside bellhousing
