Its wrong to modify these old classics, keep it the way the factory did it...............just kidding, if you want to, go for it. I had a debate with myself on weither to use sideview mirrors. In the end i decided if i was gonna have one on the driverside, i had to get one for the passengerside. So i bought both ($300 though for both together) but they are beautiful.
Once you start doing the hotrod mods though, you gotta keep going with them, meaning if your cars got shaved door handles and door and trunk lid lock gone, you gotten clean up your enginebay, take out the factory stuff (or some of it) and smooth out the firewall as much as possible.
