You know what Leo, after reading that thread I see I used the 21" as well, the 20" would not fit for me either. Yeah, the 4L-210 was the one I ended up using, the 4L-200 went back, as it again was too snug to get the fan back on. Guess with my motor being the M28/11 that worked for me as well. As you see from that thread some used the 20", so as ya said it is gonna vary from car to car, US to Euro engine, etc.

Hey Leo:
What belt did you end up running back to your AC compressor, that is still in tact and working as AC unit for you correct?
