Dave,
Very sorry to hear the loss of your close friend. As they say, keep their memories a live and they will never die! Cancer sucks! My mother in law just found out about that recently too and hopefully they got it all. If not, she has a very long road ahead as it is a pretty aggressive type of cancer for women with typically not a good outlook.
Jules has helped me when I did the conversion for the 2 spd to 3 spd wiper system on my charger. Really great guy. Certainly a HUGE asset to the car hobby as his work always was above and beyond what the other competition was. Hopefully some of his knowledge was passed on to others as it would be even a greater loss for the hobby if we did not learn anything from him.
RIP Jules!
