thanks for clearing that up for me, were there any paint lines around the axle housing for identifying something? I have seen some on cars
Around the housing ? There are no marks that originally went around the whole housing or tube on any original piece I've seem
Normally the housing itself had 2-8 different marks depending on year and style and plant . Then the center (third member) had identification, assembler, inspector and other markings again depending on year style - sometimes even marks that identified that they were filled
Guessing that "I've have seen on cars" means on "restored cars" Not something we suggest as a common practice here
Before you start marking up things, Do you have all the original machined marks and finishes right? It will do you little good to place paint daubs and marks on an incompletely finished part. Marks don't get you points they (currently) can only make you lose points. Incomplete finishes and details will cost you points every time.
