Hey. I am currently undertaking my first LS swap for my 74 nova sedan. I have a l96 and 6l90 from a Chevy Express. I am trying to figure out what needs to be done to get the trans to fit. I am pretty sure I need to cut the tunnel, but what do I do with the big gaping hole? Do I weld new metal? Are there tunnel covers for this application? I have been searching all day, and I can't find much. Can anyone help point me in the right direction?
