I actually replaced those subframe rubber idolaters with some steel pucks I had made and swapped in pre-73 leaf spring axle pads and shock plates on that car so it was pretty much like the 72-earlier cars, still soft torsion bars and rear springs but it handled pretty good, not at all rubbery and disconnected feeling. A set of some DA shocks on those cars would do wonders.
I bought a set of cast iron(?) blocks to replace the front isolators. I assume they were M/P. I never installed them, they're kicking around my shop somewhere. I replaced the 9-1/4" axle with an 8-3/4" and got rid of the rear leaf spring isolators.
If you bought an Mag GT or especially a 79 300 you basically got a limited production 2dr personal luxury copcar, with cop fuel tank, dual exhaust, leather interior, cop engine, cop suspension, cop steering box, convenience options & fancy trim.
