In the Corvette Specifications manual, page OB-12, it shows jack stand locations in front of the front axle. I currently have my car on jack stands just the way PeteZ06 has his car. But I'm thinking that it would be much more stable if the front jack stands were up front as on page OB-12 shows it. Comments????

Doesn't sound very good points to me.
I use the two side jacking points as shown in the Owner's Manual and the Chassis Service Manual. Neither, by the way, recommend jacking on the diff. I am able to place the jack stands very close to my 2½ ton floor jack (it's not a mini jack by any means) so the car rests on the stands at the jacking points. Here are a couple of pics of the car up high enough to work under.
I've been lifting the car this way for years and it hasn't failed me yet.

That's the way I do mine.

I've jacked under the front xmember and the rear spring/diff on countless cars for 30+ years with a piece of 3/4" wood so as not to dent the xmember. That's essentially the same weight transfers as if it were on all tires, no creaking, increasing gaps or frame flexing.
The owner manual and in car instructions are for emergency tire changing and the shop manual instructions are for a lift.
I use those for a lift too, no other choices.
For stand placement, these pictured is by far the most stable and again, no frame flexing.
With those jack pictured, I wouldn't get under the car, get some heavy ones with a bigger footprint that aren't sheetmetal.
Always shake the car whether on stands or on a lift before you get under one.

Hey BK... I was just wondering if I could put a couple of extra jack stands under those two metal pads in the far back, just next to the exhaust pipes, as a redundant safety precaution - you can't be too safe when you have 3500 pounds up in the air.

You could, as long as the 4 stands under the frame are put in place first. Then you'll probably find that you can't quite adjust the last 2 jackstands to contact the frame in back.
