Over the years there have been many attempts at producing a Mustang replica/look a

Wiki lists eight designs of varying degrees of faithfulness, size and price.
ScaleWings of Germany (with s factory in Poland) has been building 72% scale SW-51 Mustangs since 2021.
They're not a kit but buyers can go to Poland for a period to help build the aircraft to keep within the FAA's 51% rule...that makes it a amateur build/homebuilt which simplifies licensing and maintenance.
They have sold about 60 aircraft in the last four years and deliver 16 a year.
They're powered by s Turbocharged Rotax 160 hp engine which gives the aircraft a respectable 165 kts cruise speed.
To compare the relative sizes between the new and the old, the ScaleWings ship has a 26' wingspan, and 22' length compared to a P-51's 37' and 32' respectively.
It features a Garmin glass cockpit and comes standard with two (custom leather) seats.
