Here's the discussion regarding the F41 vs. F40 & 4leaf vs. 5 leaf going on over at Steves. I'm not sure we actually concluded anything though:

Your trim tag shows the base level black bench interior - they are some difficult seat covers to find. The best bet is to buy the material from SMS in Oregon, and have them made. You might want to buy it now, or at least get on the list so they will make some in the future. They produce it in batches, when it's gone, they wait for enough demand b4 they make it again.
Love the Frost Green with a black hat!
The 'A' on the bottom row indicates that the remaining interior items are black/painted black, like the dash pad, kick panels, dash top, etc... Keep in mind that the inner portion of the door window frames will be black on a car like this as well - it's to match the interior color. '69 is the last year for this 'special touch'. If you need a pic of this, let us know. The '3' on the bottom row indicates that your car has drip rail moldings (obvious with the vinyl top), door frame moldings, and body side moldings.
Sounds like a great car!
