installing a "simple" d series into one of my civics with only two jacks and it was bitter cold. Only could work in the dirt and grass and the morning dew made one of the jacks shift and I found a fully assembled motor on my shoulder. I was pinned for 30 minutes because I was home alone and had to wait for my friend to come over to lift it off. I was way to embarrassed to call 911. I have so many stories its not even funny but this had to be the most painfull.
