I have a 205 in my Jeep and just picked up a 203. I've ordered the doubler kit and at the same time I want to twin stick the 205. I've done a search and I have the Peterson article. Seems pretty straight forward. The only question I can't seem to get an answer to is how far back on the shift rail do you grind the notch? What happens if you go a little too far or don't quite go far enough? I know some of you did a few of these this year. How did they work out? You're help is apreciated.

7/16" is the magic number. I did this mod a few months ago and had the same question. The reason I came up with this number is because that is the distance the shift rail moves when you shift it one click.
Works great.:D

Thanks a lot.
