home processing the older ektachrome?

anyone have knowledge of processing the older ektachrome 160 g film. its
intended
chemical process is em-26, but i was considering c-41 as i have pleasing
results w/
7240 and the color negs. i know yale and Martin Baumgarten can process,
but would
like to do my own so if anyone may have experience with processing this
stock please
let me know. thought i would ask before attempting test and perhaps
ruining precious
footage.
thanks
