Motor mount question for magnum engine swaps

You guys find that interesting. Here's one for you. I swapped in reman 98 block into a 79 LRE truck. Guess what, the mounting ears for the 5.9 was the same as E58 (EH1) that came in the truck. Also, the 98 oil pan did not have to be changed for the swap. This thing bolted in a 79 fairly easy.
