will a 19" x 10" with a 79mm ofset fit a 1993 c4 corvette standard coupe

Not without the use of a spacer/adapter configuration of sorts. The actual 'fitment' could be tweaked using various thickness spacer/adapter depending upon where a person wanted to put the contact patch. I wouldn't be interested myself BUT were I to consider it, I'd likely choose a 25mm but 'fitment' is certainly a personal choice.

I agree. The stock 17x9.5 wheels have 56mm offset, and the stock 17x11s GS wheels have 50mm offset. So for a 10" wheel, you're likely to want to shoot for an offset between those two. A 25mm (about 1") would put these 19x10s at 54mm offset, and should work well. If you use just a spacer, you'll need to install longer, high-strength lugs to your hubs - not rocket science, but important.
