There is no '60-'62 tank. The '60-'61 tank fits those years only. The '62 tank is that year only—the spare tire well in the trunk floor is a very different shape/size in the '60-'61 versus '62 cars. People have swapped '63-up A-body tanks into '62s with some cleverness, but the '62 and '63+ tanks all are shaped to accommodate a round spare-tire well, not the big square one in the '60-'61 cars.
That's a real nice-lookin' medium-early-build '60 V200 you've got there, with the sharkfin chrome bits atop the fenders!
