Ok, I bought a set of "boss 302" rods, but I think two of them are not. When I unpacked them I saw that two were renumbered, but I know rods break and didn't look closer at the time. On next inspection, I noticed that two of the rods have 289 numbers "C3AE" and nothing more, while the other six say C3AE-D as I had expected. The C3AE-D rods appear to have thicker webs on the " I " portion of the beam. The seller says the difference is in the cut for the rod bolt seat, but I don't know the difference, so i have these questions:

1. What is the difference between a broach cut rod bolt seat and a spot faced seat?

2. Were any boss 302 rods made with a C3AE number, just like a 289, but they are still boss rods? That is, even hipo 289 rods are all C3AE-D, Right?

3. Were all boss 302 rods made with a squirt hole in the rod journal?

Thanks for your help as I can still recover my money (I hope) if these are 289 rods.
