My 904 pulled from a 318 question

I welded weights on my torque convertor. Trans shop supplied them.and as photo above, either side of drain plug.
I will check on buying the weights and see about getting a friend near by to weld them on, I would hate to buy the wrong weights and weld them on and have to pull the trans.. I will look in to it, my computer will be back tomorrow, my nephew is fixing it
