btw, I saw a guy on fb with almost the same build as yours.. same headers, 6 speed etc. You may have seen it.. Beau Henderson in G3 Hemi Swapped A Body Mopars. Not sure how I feel about the tunnel, but he's making good progress
I've seen his posts. I agree on the tunnel, but he is making progress and I'm not so I can't point fingers.
I went out to the garage yesterday with the expectation that I was going to have the tunnel opened up and the crossmember removed before the day was over. Couldn't wait to see the trans up in the car instead of sitting off to the side. Instead I spent all my time removing undercoating so I didn't have to deal with it when the sheetmetal is all floppy.
My plan is to split the tunnel down the middle and make cross cuts so I can just open the tunnel instead of remove it entirely and build an entirely new one. Imagine the turkey from National Lampoon Christmas Vacation movie.
That's what @72bluNblu did and it makes some sense to me, plus I don't have to weld the driver's side patch back in like he did since I am starting with an automatic car rather than a 4 speed converted car.
Now I am trying to figure out how to create a cardboard sketch of the profile of the trans when looking down on it so I can get a better idea of how far down to cut the tunnel. Will my insanity never stop??
