I did the same shift lever and turn signal arm with the ball pins just the other day on the '65 Chevelle wagon that I'm building. They work great for that. I got a "Lifetime" supply off of eBay for really cheap, they're white too! The only problem I had was that the ones I got want to spin on the shaft, so I trickled some thin Super Glue between the shaft and ball it worked. Heat might work too.
