The Hughes converter, AFAIK, is fairly new, been installed but never ran yet. Its an 1800 or 2000 stall (PO couldn't remember which). The flexplate is brand spanking new, just got it in last week from Summit Racing. Its an external balanced 454 plate with the dual bolt pattern. I've removed both of these from the K30 as I came to the conclusion that I don't need a stall converter. I'm putting the stock converter I removed (after I get it flushed) back in along with a new stock flexplate from Car Quest. I'd like to ask $200 for the converter and flexplate together. Both are brand new and never ran. Shipping will be on your dime.
