Where can I find/how to make lifted leaf spring shackles?

I have a 1970 Ford Gran Torino GT I just bought. I plan to make it into a mad max style car. I'm wondering if there's any place that sells lifted leaf spring shackles or if I'm going to have to fabricate my own. I don't know much about leaf springs(this is the first car I've had with leafs). I'm looking for about 3-4" lift in the rear, not the front. If there are any other shackles with lift for trucks or something that'll fit, that'll work. If I do have to fabricate my own, what steel should I use and how thick? The cheapest route would be the easiest for me.

Why is my car making a loud noise & vibrating?

Why is my car making a loud noise & vibrating? - 1

Added (1). When I turn the car on, it makes a loud noise. I hear the noise all throughout when I'm driving. When I'm at slow speeds, I don't' really hear the noise. Also, the car vibrates also. I feel it especially in the gas pedal. Not sure what's wrong/. Ford told me it was a motor mount and a mechanic said the exhaust needed to be changed. I did both and I still hear the noise and feel the vibration. What could be wrong? I'm running out of possibilities

How easy is it to buy and oldschool car?

I recently fell in love with two cars. I'm not really very informed on how cars work, never had a dad to teach me and never cared as a youngin. The two cars i want are the 1968 Ford Bullitt and the 1968 Shelby gt500. How much will it cost to buy one of these. With no experience in cars, no way i'm going to buy part by part and build this car. I don't care if its super fast or not i just want it to sound and run good. All this for the future i'm not getting this anytime soon i'm still in highschool but i have a good job waiting for me as soon as i start working is when i start saving.
