if it has Liberty pro-shift rings they will have welds holding them...if factory with every other tooth cut off there wont be welds and will still have the cone/taper area for synchronizer....
Another option if it is pro shifted w/liberty rings, Liberty's will face plate them now...
Liberty's pro shift rings the lugs were 1/8' wide X 1/2'' ish long and usually have Liberty's stamped in them
Doug Nash's were about 1/4''wide and 1/2'' long
