Be careful doing that with a control arm bolt -- many hardware stores will sell you a grade 2 bolt, which does not belong anywhere on an automobile. I'd be hesitant to even use a grade 5 without knowing what Volvo used -- if I could find a grade 8 with the correct shank length I'd trust that to be strong enough for the job, but it wouldn't be all that cheap or easy to do in the case of a big, super-long bolt like this. And shank length will matter here, as you don't want threads carving up the inside of your crossmember. Plus, you'll need to drill for the castellated nut. I'm all in favor of using grade 8's from Ace, but for this bolt you should just order a proper OEM one.
