I have only been able to make out the casting number on one of them. Others are rusted away. I have been comparing all 4 of them more, since posting. The line fitting is same on all, but it does look like the bleeder is in the oppisite location on 2 of them. So when re-installing I think I will find it takes one of each # on one side. I do have a manual on the way. Now finding the rubber lines, my NAPA is unable to get them.
Cannot wait to get into the rears.....ain't this fun? lol.
