I mean its not just for looks. I have a 78 and i have 4 disc breaks and a sway bar strictly for auto crossing. I mean for daily driving you won't really notice it but when your consistently breaking hard and swinging into the corners then its the way to go. OP sounds like he just wants to do burnouts and go to the local car meet or go get some groceries. Trust me spend less $$ rebuild what you have and save yourself a head ache.
