According to the research I did, the Pro Series Round, A-Frame Jack, # PSEA20000340, is comparable to the Shelby jack you have referenced. There are some minor differences.

First, they both fit the standard A-frame mounting pattern and have a 2,000 pound capacity and have a top wind design.

The differences are in the dimensions. According to Shelby, their jack has 15 inches of travel, the Pro Series has 14 inches of travel. The extended length from the mounting bracket to the bottom of the Shelby jack is 24 inches. On the Pro Series it is 22 inches. Retracted height for the Shelby is 8-1/2 and the Pro Series is 8 inches. And last, on the Shelby, from the mounting bracket to the top of the jack measures 12 inches. For the Pro Series, that measurement is 11 inches.

So as you can see, the jacks are only off in term of dimensions by a few inches at the most. The Pro Series jack would make a good replacement for the Shelby.
