67 Cuda 5.7 Hemi Tranny Advice Needed

I did all of the cutting, well actually my 15 year old son did it in about 30 minutes. When I got around to putting it in I decided to let someone else do it 110 degrees in the garage. I found a shop to put in motor tranny headers and they made me tranny cross meember and used a GM truck mount that bolted up. They did it in about 6 hours. Well worth the money at 45 an hour. Yes i even tried moving everything forward no luck.
