Default 68 vs 69 Wheels

I have a loose understanding of the differences between 1968 & 1969 vettes (door handles, door panel thicknesses, wheels, motors ...).

But on the wheels... I understand the 1968 has 15x7 wheels and other C3 had 15x8.

My question is: Could you put 15x8s on a 1968? Are the half-shafts, rotors, rear suspension geometry all the same or would the 8" not fit?

Thanks.

No problem with the 8 inch wheels. You'll still have a lot of room.

17 inch wheels on my 68 and 18 inch wheels on the 70. There's a big thread here on CF C3 about 18 inch wheels. With 18 inch wheels, you have a big selection of tires. With offset trailing arms, you can get 9.5 inch rim widths on 18 inch wheels.
