Have a 64 Dart GT slant 6 car I’m going to put a 440 in. Was originally thinking a Mustang II suspension but this is as bolt in deal and will have the right track width. Plus they claim you can use block hugger long tube headers. A little pricey but I think it’s a better setup than the mustang II. Already have a Dana 60 for the rear.
