I'm now restoring the wheels on my one owner '69 Hamtramck Barracuda with 14 x 5.5 wheels.

3 are original factory wheels of 11/11/68 and 11/12/68, and 2 are parts counter wheels of 7/24/70 and 12/23/71, because my then wife wiped out 2 on a curb.

The 3 original 1968 wheels have shallow bosses between the lug holes, and the ends toward the center of rotation are pointy.

The '70 and '71 wheels have bigger bosses with round ends.

Top 2 photos show original '68 wheels first, '70 and '71 wheels below.
