Well, I started to replace my old cracked worm gear with a new one from Mike's, til I realized it doesn't fit. Seems that the hole in the aftermarket housing is too small. I found a link on here that says the hole that receives the rod will have to be enlarged. Kind of sucks to spend $55 for a brand new part that will now have to be modified.
...Today I tool mine for it's roadworthyness test, and she passed!! Then took her for a nice long drive home, about 35 miles!! Such fun! So rewarding!!
