I believe someone used to make brackets that would make the SN95/New Edge (v6 & GT) brakes fit on 64.5-70 classics. However, they stopped making the ones for the front brakes. It is possible, but you would have to either fabricate your own brackets or find a used set of them somewhere. There is likely a company that still makes the brackets for the rear end. I am not 100% sure, but I think the brackets for these were made by DazeCars. I could be wrong, but you might wanna start by asking him about it.
If I can offer a recommendation, I would recommend selling your '01 GT brakes to the fox body guys and getting some 13" Cobra brakes for the classic. You can buy brackets for that conversion from Mustang Steve or Vintage Venom. One draw back with going with Cobra brakes is that you have to use 17" wheels or bigger. It has a bit more support on these forums.
Good luck either way you decide to go.
