67 Barracuda- Brakes and suspension on a 5000 budget- advice needed

Dig into the wife's retirement account and treat that good old car to a set of stainless steel flex brake lines, 2 front and the one in the rear.
They last much longer than rubber lines and they dont ballon out when you stand on the pedal making for a nicer feel in the brake pedal.
Wife has NO retirement act nor I Just 2 old people she still works country r/e at age 65,she is a kid! ha
Never had anything stainless on one of my old mopars in 35 yrs! I have always had several cars working on and IF I had just one, I could do like many, try to make my "baby" perfect!!!
