Torque converter weight conundrum!

Yes as I mentioned at the beginning of this thread that most of this has been discussed and that a little more info is needed, well for example the exact location. That b&m flex plate is $101 and a new torque converter is $89. I'm hoping knocking those weights off the 904 and welding them to the 727 will cost me $00.00 :D thanks for the help as always...
Just for future reference, I've never bought a B&M flex plate. I've always had mine balanced from a good machine shop. I believe I paid 45-50 bucks. I'm down to the last one, the one in my Duster.
