Thanks for posting. I bought both Comp tools based on this video. Worked on my 1966 Cadillac 429 engine. I just had to add more spacers as the add-on adapter was too short, only 3 inches. Otherwise worked fine.
interesting but somehow the tool is not proper designed to the end. They should install a SLOT or 3/8" socket into the parts so you can remove them easier and quicker. My biggest problem is on most installs the force you have to crank it onto the shaft is so great that a single short wrench simply won't cut it. We work most the time with 2-4' extensions and breaker bars to press fit them proper in place.
