Tale of two cross members

Maybe the smaller bolts were less expensive, and strong enough, and that's why they went that route. It seems like such a little thing such as maybe .10 cents cheaper per bolt and per nut, but times that by 4 bolts and 4 nuts and that's almost $1 per car savings times how many A bodys built that year? That's the type of **** bean counters do to shave off costs. A little here and there it all adds up over time.
