Different vendors sell these, including eBay.
You only want a 10 spline. Don't buy a 14 spline by mistake.
I bought mine from the 1st vendor below because he spent time on the phone with me to make sure it was what I wanted. Made some measurements and called me back, etc. He deserved my business.

This one is on eBay and a good price.

BowTieTim reminded me that there is a Tech Tip Article about the Jeep shaft swap. I had read through it more than a year ago but didn't think it would apply to me because I don't have a foot pedal starter. Others folks deserve credit, not me. I'm just documenting it with some photos.

The part number listed in the article is 1351085008. A Google search using that number will get several hits.
