I was wondering, if you had a complete car, for instance I have someone who will give me his early 70's ford wagon, could you take the disc break components off of it and put it on your mustang. What would stop you from just taking the whole break system off this car and putting it on your mustang. Also if the car that I took them off of was front disc rear drum how hard would it be for me to convert the rear to drum after I did this. I am just trying to find the cheapest way to convert to disc breaks. All around eventually but just front to start. I was hopning that in time I could also use more performance roters. Thanks.
