Where does this go?

If the welds look like chicken crap they probably didn't use a mig welder. They probably just used a regular wire feed welder. Ask me how I know. Learned it the hard way. As far as finding new strikers you might try The Paddock, or Layson's, or Year one for new ones. Or if your into E-bay you might find some there. I bought alot of good used stuff for my Cuda off of e-bay and had pretty good luck. Out of about 150 transactions only about 2 or 3 weren't good and they didn't cost much. Just gotta read carefully and look at the sellers feedback.
