  I have two, one
stock and the other I uilt in 78 both look good but the
'78 one has all of my mods from years of use.  FYI: the mods stay! 
 And those mods, being common for that era and being done by
the machine's original owner/builder, would just add to the machine's
character and history. 
 
Since the history of that one machine is entirely mine from day one
I can even vouch for the reasons behind the mods.
