Query: Great but for one exception

First off-great price. Second fast shipping, I got it in 3 days. Most importantly This product works. It's installable by a shadetree mechanic, and his two sons with normal tools. Now all that, to my judgement, rates 5 stars. However, the brackets for the alternator are not marked. Worst was that one of the threaded brass inserts to attach the throttlebody was badly galled. I had some anxious moments oiling up a screw to chase the threads. I think the threads may have been contaminated with something non-metalic, because the screw's threads were not deformed in any way. I would buy from the manufacturer again due to price, and overall quality.IMHO if the brackets were marked this would a perfect kit, because I doubt the defective threads are a common quality problem.
