People may jump all over me for this, but whatever.......
Forgo the B&M and try and find an OBX Shifter for a Focus (2000) on eBay. it is IDENTICAL to the B&M, no lie, I know, I have one! And it comes with a shift knob!
http://store1.yimg.com/I/eracingworks_1815_4470307People will say they break, but here is what you do to prevent that (and it will cost you less in the long run, compared to buying the B&M); if you look at the lower ball joint on the shifter you will see that its kind of pressed into and spot welded into the shifter arm. That's what breaks off, but don't fret. Take the shifter to your freindly exhaust shop and have him MIG (or TIG if you know someone who has and can use one) weld the lower ball joint to the shifter, around the base of it, so it's stronger.
Then install it and shift away. It wouldn't cost more than $10 to have it welded and would take 10 minutes max, to do.
That's what I had done to mine and it's as strong as an ox!
