I went through this myself a few weeks ago. Although NAPA shows the spring eye bolts on their website I was told they are no longer available. They also told me I got the last 4 shackle pins too which were shipped from another state. I ended up getting the eye bolts through LMC and they were only like $4.95. I didn't look for where they were made- I was just relieved to have found some. The quality seems very good to me, they are black oxide treated and do not have a shoulder problem like Denny Graham described in a post about the aftermarket replacements. The LMC bolts torqured up just fine and I am quite pleased with them. Not sure why everyone else is asking 6 times as much for an inferior product.

I got all my wheel cylinders, shoes, and drums through NAPA and all parts were cheaper than the AD vendors.
