Spirit of 76???

[Jpar]

Hey guys what's up ! I'm new to this site and I have a question that I would like your opinions on. So I just bought a truck last week not knowing exactly what I was getting or at least suspecting .. I bought a 1976 swb 4x4 with spirit of 76 emblems on door I've been trying to do research but I can't find to much info on it.. I guess my biggest fear is starting to do work on it say lifting and adding other stuff to it that doesn't need be if this thing is really a legit "spirit". Any advice or opinions would greatly be appreciated...
