sigh. fucus, i guess you didnt search TOO hard when you were looking up threads on this....
I created these threads a long time ago, first a DIY....then a full STS thread. Apparently they were not read. Please see below.
How-To: DIY STS
I did the above in 2008. Then, I did this:
The Definitive STS Thread!!!
I had asked that these be stickied, but it seems they never were.
And I can't get no love. =( I tried to put in as many 'searchable' references as I could in each of these (such as Short Throw Shifter instead of STS, which does not come up in search). I had hoped people would see them in their searches, but apparently not. SoCon, please refer to my threads for the answers to your questions. Most every question is in answered already in these two threads. It was THOSE threads where these all first came up. This discussion/thread came up about a year later, in 2009. Then was revived.
