Getting ready to swap a 5.7 into my 73 Dart Swinger

That was likely mine 6.1 into 72 Demon March 2018. Thread is in hemi swap section
Ok it was ur thread and ive read it a few times now and g50 did it to the frame connectors I can recall his too. But there was one more I remember seeing. They used a u shape piece of rectangle tubing for the upper half of the mount and there was something about tubing . I'm dying trying to find it. But i kick this off tomorrow
