Small Block Trans To Engine Support Braces

I have studied 67,69,70.71,73 and 74 parts books, and they show that the 904 and the 727 use the same braces. But you need to know what year your engine is. Around 1976 they moved the bolt boss forward 1" on the driver side for the new longer starter. I think the original pad is still there, just not drilled and tapped.
