73 duster front end swap

I've been digging around Google a few days now and have been seeing contradictory info so I thought I'd ask here.

I'm wanting to change the front end sheet metal on my 73 duster. I don't like the point on the front. Prefer the straight front end look.

I've been looking at the demon front end parts. This is my forst mopar car build so I'm not sure what all interchanges. I saw a completely flat front grill without the demon split between the sides but forget what model it was on. Anyone know the grill I'm talking about?

Will I have to change my 73 fenders or is there a way to modify them to work with the demon lower valance and bumper?

I'll have tons more questions I'm sure. I'm in the I love this car wheres all the money to buy parts phase of ownership currently and have hit brain overload while looking at parts and scheming the build.

Any and all help is appreciated and hey if you've done it I'd love to see front end swaps on your dusters too. Doesn't have to be demon specific as I may like your swap better so let's see them.
