If the PAL version was a frame-to-frame transfer, and is thus running faster than the original film (25fps vs 24, or even PAL video at 25 and HD video at 23.98), the key is to first get your stems back up to film speed, which would involve an SRC using 47952 as the source sample rate. THEN, when it's back at film speed (48k), you could do the NTSC>PAL SRC, the 4.1% thing. Maybe? Try just the center channel using the fastest setting as a test, and if it works you can do the whole thing at "Best" quality. Of course, the pitch will be faster (about 1/4 step) as well, in sync with the faster speed of the film. To get it in sync but at the original pitch you have to do a whole time-compression/pitch-shift thing which is a whole different process.

25 to 23.976, Divide those two numbers, and you get 1.0427093760427093760427093760427. When truncated and expressed as percentage, it becomes 104.27094% which is the number that you feed time conversion software such as, Prosoniq Timefactory or Nuendo timestretch

NTSC to PAL would be 23.976/25 = 0.95904 = 95.904%
NTSC to PAL SR = 48000(25/23.976) = 50050 rounded.
PAL to NTSC SR = 48000(23.976/25) = 46034 rounded.

A time-stretch version is recommended, vs SRC conversion.
MPEX2 in Nuendo is apparently a good tool.
