Torque Converter question

I agree with plymouth65 regarding off the shelf availability, there is none. I had one built for a car by a local converter rebuilder and fellow drag racer. At that time when an aftermarket converter was $400 my special one cost $695. I'm sure the costs are even higher now. To me it was worth it because I'm a push button "Junkie" ! But I should add this was for a track car primarily used for bracket racing and not used a lot on the street. It's a tough call, my two cents.
