$42.95 at Summit and unlike the Northern Tool copy, the center shaft in the Summit model fits many common jacks without modification!

I also afixed rubber to the top of the crossmember because the extensions are useless for jacking the front.

Wish I had known that before I bought the one from Northern Tool. Luckily, I have access to a toolroom and I was able to modify the shaft with an external boring tool in a milling machine. PIA

I lopped off the threaded adjusters from the plates on each extension and then welded each plate to the ends of the center section. I then reattached the rubber pads to the newly welded plates using the original mounting screws. This works perfectly on the front. The extensions I now use as resting places for a pair of 6 ton jacks which securely cradle the entire setup. Works like a charm on the front.

Modify one for the front, and keep one stock for the rear.
Then you can lift both the front and rear at the same time, get the whole car off the ground when needed. Also handy for keeping the car level when changing fluids, etc.

I use a Craftsman floor jack and modified my Northern adapter like this.... It works fine for both jacking the front or rear of the car. I modified my jack stands to fit the channel that the Northern adapter rests in. I never remove the floor jack to work on the car unless I absolutely have to. Most thing you don't have to remove the floor jack which simply is another safety stop in case of a problem. My idea did require welding a pin on the channel so it would exactly fit the hole on the floor jack. Not a big deal but I can change the jack back to the original configuration in about a minute...

You buy two crossbeams.

I first used this combo when installing my insulated tunnel plate a few weeks back and felt very secure under the car when using the cross beam adapters with jackstands cradling the extensions!
