Rear Axle Identification

I wondered if maybe it was a later year deal with the T block position. I bought stuff to just make my own lines previously, but I don't have the tools to do a double flare, and i found these pre bent lines for probably the same price it was going to be to get the tools. I just double checked the listing and it says 70-73, so maybe it changed in 74 or something and I'm just "lucky". I don't think I've managed to buy a part yet that I could just bolt on to my car. It's a Frankenstein already since it's a 67 with 69 fenders and grille, but going to the part store is always fun since I get to tell them a different car for every part, lol.
