Ha, if your ever replaced a door cover or a rocker panel, have to do a lot of drilling, best to use a spur drill.
Had to replace a bumper bar on a 86 Honda, wanted to attach a small trailer hitch to it. When I removed that plastic bumper that looked good yet, that bar, a natural trap for this dam road salt, was nothing left of it. But this was back then when they haven't skyrocketed the replacement parts like they are doing today. That was just a bolt on.
Have no idea why that Cruze needs those dinky little tabs, could have used bolts, but a hail of a lot cheaper to spot weld than to pay somebody to screw in a bolt.
Ha, the 30's vehicles I have owned used spring steel for bumpers, hit a tree would just bounce back with no damage, could also give a guy a push start as long as the bumpers matched.
Also the vast majority of cars I have owned used a bumper jack, talking about 5,500 pound cars, add this to your history book. We also used to have a law where bumpers had to pass a 5 mph bump into a wall without damage, more of history.
Cars today, Cruze is one, tap a wall at 0.01 mph, that plastic bumper would shatter like glass, find far superior plastic on these blister packs that once used ends up in a landfill someplace.
When us guys that were planted here in earlier times that say, they don't make em like they use to, we know what we are talking about.
You could drill out those eight spot welds and replace them with bolts, but don't show these bolts to these new kid engineers, they won't know what you are talking about. What in the hail is a bolt?
