Hard to tell with that small detail...... I don't think it's a '65 though, which was the last year for that body. The grill on the '65 was a bit different. There were differences in the grill for every year, but the '62-'64 grills were fairly similar. What could tell for sure would be the tail lights. '62-'64 the same; '65 was different. '62 Grill: '63 Grill: '64 grill: '65 grill: '62 - '64 wagon rear (center emblem might have changed each year... This particular one is a '64): '65 wagon rear:
Okay, now we've narrowed it down to either a 3 or 4. We'll just have to wait, until Grizz brings it home, unpacks it and puts the grill, tailgate and all moldings on a scanner
