Yes but to put the turboprob in the P-51 it had to basically be rebuilt and this was not until 1967. The P-51 proved to be so useful that in 1967 the Mustang was put into production once again, this time by Cavalier and Piper. The Cavalier Turbo-Mustang III and Piper Enforcer were developed as Counter-Insurgency (COIN) aircraft with duties including light attack, Forward Air Control and interdiction roles.
