Luckily they are easy to change. When mine broke, i rebuilt it, and used it for like 2 months before i ordered mine off rock auto...
It broke off at the head a bit higher then motodeficients did, so I was able to use a lathe to drill a hole dead center, then I tapped it, and threaded a bolt into it...
Here is a pic...
I still have it, saving it as a spare, but i put a new one on.
