I bought these for an a-body Mopar because the factory ones were showing a little wear. First only a couple of the cam washers actually fit over the bolts. I tried every combination but the holes in the washers were just not big enough so I had to file the openings until they finally fit. Then when I installed and torqued them to factory spec the cam washers actually bent a little bit. I removed them and took them to a local shop who tested their hardness vs. my stock ones. They recommended that I stick with my stock ones despite the bit of wear as they were substantially stronger and these seemed very cheap. They prob would have worked fine but IMO these should be grade 8 hardware.
