issue with AMD Demon floor pan..please help newbie

hi guys, so this is where i am at now, i think the fitment is good now, i just have it held in place with clamps for now.
i would like everyone opinion on it. the gap around the trans hump is about 1/4 inch which i know it can be pushed down at the top with some force, as for the sides there might be a small gap, how come they dont weld on the sides of the hump? if there is a gap after its welded will that be ok?
