You'll have to weld another bottom tab to attach the strap to. You can grind it off the end one...
Teg is right. The 72" model does not have the corresponding bottom brackets for the 2nd and 3rd upper tabs. Cutting a length off of the end of the 72 would leave you with only one bottom bracket and therefore only one strap could be used.
Looking at the installation instructions on their website, it appears that the 52 inch model does have all 4 of the bottom brackets. I don't know why the longer version has just two.
