according to my search, this is for 360 magnum(5.9l) with external balance, using 904 trans. my application.
was hoping i could find one before i use neutral flex plate and having correct weights added to my converter.
i know they havent been made in awhile, but that being said,i have one for 360la(non magnum). i bet the only difference is the size of the notch which would change balance weight.
