I never had an original BB truck but I thought the style in your first pic started in '73 models.

I had a 67 that I installed BB on the SBC stands. The headers didn't fit and there was plenty of grinding on the frame and hammer work on the pipes.

In the mid 1980's I wanted to install another BB in a '72 and went to the dealer and purchased the stands you have in the second pic. Yes it moved the engine up and forward.
