Hello, new here

Looking to do some suspension work and purchase new wheels/tires.

I have a 65 coupe that has the E2 body kit. Because of that, I'm not sure how far I can go related to frame modifications. Everything is molded together so taking off fenders and front bumper isn't an option. Is there an option out there that would eliminate the drum brakes and convert to disks while lowering the ride height? Everything is essentially stock. No power brakes or steering but will update power...
