This radio has the same circuit board. It's a mobile version of your radio, more or less. Alignment should match it.

Bear in mind that alignment may expose defects in a radio that's nearly 40 year old. If it has been stored in a humid environment for long you may see adjustments that just don't do what they're supposed to do any more. Trimmer capacitors will become "noisy" when you turn them, like a scratchy volume control. Tuning slugs may 'bottom', not at the physical lower end of the coil, but with the slug dead-flush with the rim of the hole. This suggests the built-in capacitor inside that can has gone bad.
This is why alignment is the first step to diagnose weak-receiver or weak transmit problems. An adjustment that won't respond correctly points to trouble in that stage of the radio.
