If you have any interference at all, it will be at the lower front corner of the fender (in front of the tires) - typically only with the wheel turned out, off-road, with the suspension compressed at that corner. If you don't mind a little hacksaw trimming, it's easily fixed and barely noticable. Chances are with 8" rims instead of 10", you won't have any problems at all. I'd say go for it - that's a great size for a K20, you won't regret it.
