issue with AMD Demon floor pan..please help newbie

so i have started to weld the floor in place, started in the middle of the cross member and working outward. evreything is looking good so far. there is still a slight gap down the side of the trans hump on the passengers side. if i push it in by hand it will touch the crossmember. so i was wondering would it be ok to weld the side of the trans hump as well. amd told me "floor only needs to weld on the horizontal surfaces of the cross member" but i dont see it hurting anything to weld on the side as well. as i want i flush fit.. just thought i would ask and get someone opinion : )
