Thank you oh Search God. Actually I did search and in the last two years only found 20 posts dealing with 1 piece vs. oem. about 5 had to do with installation. 5 with general questions that provided no answers and maybe 8 dealing with driveline vibration from 1 pieces which is what I was worried about. If you consider 2 threads in two years that partially answer my question beaten to death than try getting that prescription refilled.
