Gavin, I would like to give you a definitive answer, if only I could? I am not sure I will be able to help, but will tell you what I do know. I have no real 67 bb experience, I have, though, messed with several 68 & 9 bb Camaros. The cross member is the same whether manual or TH400 for an 68 & 69. This would tell me that the mount positions would (should) be the same. The main difference as I understand (and I'll be corrected if wrong) is the 67-8 mount is narrower for a different engine mount than the 69. I also understand that the 67-8 driveshaft is a little longer than the 69? I never quite understood exactly where that length was achieved , but I never questioned it either, I just accepted the fact? But since the cross members are the same and subframes interchange, I have to assume that the driveshaft length difference is due to the rear and where the springs are positioned on the frame rails, because the rails are different between the years? Regardless, irrespective of the engine date ( you said you have a 69 engine) I would use the mount called out for that year of car that it is supposed to have, i.e. Use the 67-8 mounts on your 67.
