Welcome, I know the feeling. I bought my 70 Duster new(gold duster), 318, 3 speed manual, 3.23 open; as insurance wouldn't let me get the 340 4 speed, 4,10 gear, that was $300 cheaper, lol.
We still know how to work on these cars.
Congrats, the sanding will get old, fast. then a breather, and restart.
I just sold a 40 Ford F1; when the guys that came over to pick it up, saw my 70 Duster, in my shop; I had to almost beat them out of the yard.
Patience, grasshopper...
