I am changing over the wheels to knockoffs and wanted to know where i can jack the car from ?I want to raise the front 2 tires at same time and then the back 2 at the same time .The car has side exhaust also
thanks Mike
When you run your floor jack under the rear end, just make sure you don't knock the edge of your spare tire carrier.
I would jack it up by the cross member in the center of the door but you didn't ask that.
Mike, you must be the guy who placed a floor jack under the cross member in the center of the door and crumpled the bottom of it on both my cars. That would likely lift the whole side of the car, but the cross member isn't strong enough to support that weight without distorting. Lift with the frame as described in the owners manual. Or the front cross member with board to span front and back edge of it. Or the back under the strut rod bracket. Again with a board on jack pad.
Like this - per the shop manual:
When in doubt read the daggone manual
Put a jack (rolling or bottle jack) as indicated on each side for the front, alternately jacking a few pumps on each side until that end of the car is airborne - you don't want to get the frame in a twist..then do the work for that axle...
Jack the front down (alternating pumps again). Then do the rear the same way...
Place wheel chocks on the wheels on the end you are NOT currently jacking up...

Jack on the frame railby the cross member. Not on the cross member. The jack would slip off.
Sorry about your hard cheese luck. Maybe your cars have rusty frames? I've raised more than one C2/C3 at that point without any issue. I left out using a small block of wood too. Don't jack steel on steel. It'll slip. Use steel on wood for added safety.
I don't think it'd be a good idea to put jack stands under the front frame horns and especially, under the rear of the frame where the bumper bolts on. I wouldn't get under the car if I did. A rusty frame at the kick up's might let the car down on top of you quicker than you could move.

New car, new frame, different story.
I don’t do that either. I should have specified more clearly the shaded frame areas along each side rail. As indicated in the drawing. That’s what my narrative was referring to when I said “each side”.

All of our race C2 and C3 Vette's and my street C2's we jack in front of the cross member on each side and place the jack stands where Frankies pic shows the floor jack, jack stands. Literally hundreds of times a year!

my frames are harder than your head. The frames have dents from stupid jacking, without wood blocks. But, that's it.

Maybe you shoulda' read the owner's manual before you raised the car or just start working on it yourself rather than farming it out to those that don't know what they're doing. I'd guess you should buy a four post lift to avoid frame damage?
My frames don't have any dents in them including the front cross member. and the few times I've jacked them up, I've done like I advertised.
What we thought was a virgin California frame before it hit the salty air on the coast of Virginia. Beware of jack points. If you have a frame that looks like this or even remotely like this, don't jack it up anywhere and get under it. No more needs to be said.
That was a lot more than a "hit" of salty air....more like the car went swimming in the Atlantic...
But yeah - that's where they break; here's a gem in front of a forum member's garage:

I was more thinking about that guy up there in Virginia that has dented frames on his car. I understand he left California for some reason? Never did find out why.
If they break there, you can almost bet the middle of the rails are weak as well.
How'd you like to get hit in the rear in a car that had a frame like that? Or stick a high powered engine in a car with a frame like that without first verifying the frame integrity.
I betcha' there's more than one out there like that.
