It was not my intention to tell another member they were wrong, I was speaking Klingon: you were speaking Romulan. I was talking early A small block brackets, you are clearly showing 67+ era units. What I am trying to say is that we are both correct for our respective model year applications.:read2:
No harm no foul, and actually my proof was provided indirectly by Neil at the beginning of the thread and later in the post from the Early Valiant/Barracuda site. My slam was towards the Mopar Chassis manual author, as it was the errant descriptor. My apologies to anyone who took my explanation of the modification to the factory early A brackets for use with a 360 as an insult.
The thread got sprinkled with pre and post 67 A-body responses (which you pointed out in a subsequent post). My biggest error was not first asking the question about whether the responder was talking about a set of brackets from a 63-66 K-member versus those for a 67-72 K-member before posting.
Lesson learned.
