The Oil Level Gauge, commonly called a Dipstick, differs between early and late A12 engines.

Overview

Short: ~9-1/16 inches from tip to bottom of rubber
Long:

If you rotate the A12 dipstick 180 degrees and put it back in, it hits the crank. Makes a crazy slapping, tapping, whacking noise.

Early type goes directly into block (1970-1973) so uses a short stick

H10 version is used by front-distributor A12 engine.

Late type goes into a tube which is inserted into block (late 1973-up)

H50/H72/H95-type gauge is also used by B210 and B310 A12/A14/A15/A12A engines.

Oil Level

Oil should be between H and L marks.

Marks are the same for early (H10) vs late (H50) gauges, even though the overal gauge length differs. That's because they use the same oil pan! The oil level from the bottom of the pan is what is important.

Tube Removal

Use vice-grips and tap it up and out while twisting back and forth.
