904/trans dipstick same as gm700 r-4?

Called a few trans shops looking for a dipstick for /6 225 dart 904, basically told me good luck. Found some on fleabay that says they fit chrysler 904 and gm 700 r-4. Anybody know if they're the same dipstick? I should be able to find one for a 700 r-4 locally I'd think. Thanks.
