------Not trying to change your mind so much as inquire why you would put a narrower wheel on the front than your Corvette came with, at least in 69??? There is no difference between 68s and 69s anywhere as far as clearance is concerned. I have put more sets of aftermarket wheels on Corvettes than most and over the years I have migrated to 8s or 8 and a halfs all the way around. Depending on your tire choice you definetly wont have any problems with clearance. The 8s also give your car that road-racing flair that I kind of like on a Corvette.
