Actually using quick jacks ?
I've wondered if the quick jacks we use today could actually be used to lift the car. A friend was helping me work on the car one day, I went to take a piss and when i came back, he was using my floor jack and quick jack to raise the car. 
The quick jack held just fine and did not hurt the body ! 
I don't know if I'll ever do it again but, if it held with no problem, I'll ask what about using it to tow a short distance, at slow speeds ?
The pressure and weight would be more to raise the car, than pulling.
Has anyone towed their car before using the quick jacks ?
Or used to raise the car ?
What are the differences from the racing cobra back in the 60's vs todays after market quick jacks ?
Anyone have a pic of the original quick jacks ?
I've seen the leverage tool on little wheels used to raise the car, but not just a pic of the quick jack.

I believe that Kirkham website advises against jacking with the quickjacks. Saying that even an orignal cars bodywork will be damaged (which was not really a concern for a racecar in the 1960s).

Here's a thread where this was discussed.
Does any one use the quick jacks to lift?
...and one more with some pics.
OK has anyone even seen one of the quick jacks?
Luckily it didn't tear the front of your car off.

The original qj's weren't what we'd call servicable. Yes they were used, and yes the body got some wrinkles, and no they really didn't mind that much.
I've often thought that there isn't any real reason that they couldn't be made to work - just haven't got around to seeing what it'd actually take.

You are lucky the quick jack did not bend and damage the body of you car. I have seen it happen.

towing with quick-jacks
I towed my ERA home one day by the quick-jacks. Blew up the tranny (one out of three times) just a few miles from home. Used a couple short "axle strap" tie downs to wrap through the quick-jacks on each side, and linked them together in the center with a tow strap. Worked just fine, and did not damage anything. Can't say I'd recommend it for a tow of any distance, though.

The quick jacks are more for originality than function. I never put them on mine but used the bumpers as I thought they looked better, But the way mine were mounted, it might have been possible to weld a re-enforcement brace to the frame and rod that stuck out to mount them on. Also I have seen different kits that have different lengths of mounting rods, so it would be hard to make them work with no flexing.

I broke a lower ball joint last year and the car came to rest basically bottomed out on the frame on the drivers side. Fortunately I was only going about 20 mph when it happened.
There was no way to get a jack under the car and lift it up. To get the car off the ground and try and get it into the car trailer, we found a 4 foot long piece of roundstock and jacked it up using the quick jacks.
The quick jacks flexed a little, but not much.
