A Good C3 Day
I have had my 17 inch wheels for a couple of weeks, but the stance has not been right. First, tried to correct this with 8 inch rear spring bolts and it still left the rear up about an inch too high.
Based on advice received here, bought the C4 10 inch bolts and ended up cutting about an inch off. My spacing from the top of the tire to the lowest part of the fender well is two inches all around. On the rear of the car from the middle of the bumper to the ground is 1/4 inch higher on the passenger side. Gotta work on that!
Did a Mobil One Synthetic oil change with the K&N Filter.
BTW, I love my car more than I do some of my relatives.

Mark, I think you have one of the nicest c3's on the forum. I really like the combinatiom of the Black with side pipes and TTII's. I have a 69 that is also Black with factory side pipes and have been considering putting 17x8 TTII's on it. Did you have any clearance problems with the 17 inch rims? Also, how do you like the Kumho tires?

About your comment that the passenger side was 1/4 inch higher.
The Corvette shop that I was talking to about aligning my 68 said that as a part of their standard alignment procedure, they weighed the car at each wheel. In addition to being aligned, the two back wheels should have the same weight reading and the two front wheels should weigh the same each. So.............if the passenger side of your car is 1/4 inch higher, this is sort of a cosmetic problem if the weight on the two rear wheels is equal. If the weight distribution is not equal, there is a spring or frame straightness issue.
Measuring rear wheel heights should also include a driver's weight.
I once had an alignment issue with a 69 BB. Continued alighnments didn't work. The alignments were apparently OK except that the car would skid sideways on a full force break petal application. Finally the car weight at each wheel was measured. This revealed a slightly bent frame and a bent spring. This car had been involved in an accident and had an excellent repair job that left no clues...except for the tweeked frame and bent rear spring.
For body/frame alignments..keep in mind the option of weighing the car at each wheel.
