Don't give up yet. I came to the conclusion that none of these shift kits are perfect anyway, even the SBP stuff needs some improvements and tweaking to really work properly. Just take the time to really plan everything out as best you can with the advice you can get from Jerry or other members that may have some knowledge.
I don't have any myself, but I do like when people post threads like this because it is a great window for potential insights and information I may have missed in older threads or other research I have done.
