when i called him a while back he said they don't sell the adapter separate. you have to buy one of their transmissions then the adapter too. i figure someone has to make it for them, just don't know who. for their mild street trans its $1900 and the adapter is close to $800. kinda sucks because i know i can get and do the trrans dirt cheap if i could only buy the adapter bell housing seperate.
