WTB Torque Converter for H51 Hydramatic

It occured to me to ask if someone has a torque converter for sale for the Hydramatic trans and to ask if they are the same 1951-54 or if single range / dual range made any difference, or any other changes. I know Bitburger has the whole trans assembly but I just need the torque converter having a 1951 rebuilt Hydramatic trans. Thanks Gert
