Just received some 3/8-24 grade 8 bolts in various sizes from McMaster Carr and couldn't be happier. They have every size and length. And the bolts are made in Canada, not China. They are chromate yellow finish but if you don't like that it is a simple and quick operation to remove that yellow color with vinegar or any other acid so they resemble the OEM gray finish. Grade 8 is way more than adequate, and a good replacement for those corroded/questionable suspension bolts I have to replace. Shopping was easy and shipping was fast. No, I don't work for them.
