That's the way I've always done it. I wrapped the ubolts with some electrical tape too, for a little more grip. With how big my headers are, I don't think the actual tool would fit.
That’s another issue with the manufactured tools. They don’t fit in very many places if you have headers. They also aren’t really made for bars larger than 1” or so in diameter, and don’t fit those very well at all.
Combine most headers with large torsion bars and a non-stock oil pan and even just getting the tool on the bar in a useable spot is just about impossible. And of course, totally unnecessary if you just use the LCA to remove the bars.
