69 chevy c20 lug nut help

[treveiger]

Hey guys, I got a 69 chevy c20 and the PO said he put brakes from a 71-72 on it if Im not mistaken. Today when I went to take the tire off I noticed it looked like the front lug nuts were bigger than the back so I checked and sure enough it was. We're looking at getting new lug nuts so Im trying to figure out what size these things are and what year there from. Im also looking at getting front brakes sense the brakes are on there way out, are the disk brakes from the 71-72 the same or are they different? Im not new to trying to figure out what the PO did to this truck so this is no surprise
