Stupid question for the day

I have a 904 behind my 360 magnum. I used the stock flexplate but needed to enlongate one of the converter bolt holes to work. Magnum converters have symmetrical bolts while the older LA stuff have one bolt slightly off. Unfortunately nobody makes a flexplate to mate a 360 magnum to a 904 anymore. The easiest way will be to use a neutral balance converter and a magnum flexplate with the balance weight already installed (97-up I believe).
