Disk brakes....YES or NO?

[fastsvo]

Hey guys, I am currently in an internal struggle with myself to swap the
front drum brakes on my '67 Fastback for the Granada disk setup. This car
is pretty much an original car (color is not original...thats it), but not a
fully restored vehicle and will never be concours. Currently it's my daily
driver, but will soon be retired for weekend cruises....at least that's the
plan So, in being the super anal original type person, would I loose big
bucks on the value of this car or maybe increase it (as one person told me).
I will obviously keep the original hardware. I've concluded that adding a
booster is too much hell and will keep them manual. What do buyers of
classic mustangs like to see? Thanks for the help!
