There is no need to do the rears, they are sufficient in most instances. A front disc conversion will absolutely amaze you and should be able to be done for less than $1000.

My '69 scared me to death to drive around in tight traffic because the drums, but the disc conversion cut the braking distance in half I bet. My rears tended to lock up quickly with the drums, but none of that since the disc conversion.
