Tremec TKX first cuts

I used 2.5"x .500 flat bar across the top and 3/16 to tie into the lighter weight cross member. I tried to keep it low profile and simple. Seam sealer down the sides should look clean when done?
When the transmission mount is not in place the material does not look as big.
Thank you! My plan is along the same lines, but I am going to section the floor pan hoop I have, along with a second one and make one larger one out of the two. At least that's the plan. lol I am putting a World Class T5 in my car.
