I've been reading through the forums and have been getting confused with what shifter extension length I should be getting for my swap because it seems like people interchange the w58 and r154.

In my case, I'm swapping a 92-94 W58 into my 97 auto sc300. If I want to use the same hole as the auto trans and not have to make any cuts in the tunnel, how much do I need to extend the shifter and the linkage?

I have not had the chance to test fit everything yet, since it is my daily, but I will be soon. Thanks.
