With or with out a hood scoop?

That is my future plans, don’t you have to make up bumper brackets to put a 72 rear bumper?
So me not knowing your skill set, so keep that in mind. I tucked mine in as well and powder coated them black. There are a million opinions on the chrome no chrome but you asked specifically about tucking them in. It is very easy to do with your existing brackets, literally all you need is a grinder with a 4 inch cut off disc and a welder, and some patience of course. I mounted my factory ones then measured how much gap there was between bumper and body then cut out that dimension less just a bit so that they did not rub. Then lightly tack the two parts back together and reinstall, watch for “pitch” of the bumper. You may need to do this process a time or two but it does not take a lot of skill just some patience and it is much easier with a spare set of hands. Once you like it weld em up good and powder coat or rattle can or whatever paint application you desire. They are hidden so even if the welds are not perfect it is ok. Feel free to PM me anytime should you ever want metal fabricating type advice. This forum just has a wealth of guys with a lot of skills and all you have to do is ask and they will help.
