HF has 2 different wheel chocks..... I got the cheaper one for my lift (when I had it) but ultimately mounted it to a piece of 2' x 3' diamond plate (plywood would work). I also have a LA Chock (which I had even before the HF chock) and HF also has one that looks and works similar to my LA Chock for a darn good price....
Here are the 2 different ones they have.... and I would opt for the 1st one (use a coupon too).
