Homemade chin spoiler looking for some feed back please.

My '74 shock mounted bumpers do have the tab. An eyeball check makes it look like they are even in about the same spot as the tabs on my '73. Next time I am in the shop and can get under there, I will try and get a center to center measurement to compare.

BTW, I suspect the shock mount at the bar behind the bumper will be in the way.

Here are some pictures from the bottom.
