im sure they have it on that site
just make sure you get the right one, i think there are differences b/t many models and mixing and matching does not always work

 

yep, i just searched for wisconson manual tranny and found a bunch. hope this helps

 

I feel your pain, I still need to change mine, but I'm putting it off.

They aren't replacable or not easily at least.Do a search there's a guy on here with a write up on how to replace them.Mazdatrix sell new ones thet have replacable ones in them.
