I bought a Unisteer Rack & pinion Kit for my 68 Vert. The Rack mounts behind the front crossmember using the 2 rear lower control arm bolts to bolt it to the car ,they supply 2 longer bolts for this .When I got ready to remove the old bolts, I wire brushed them and noticed they were grade 8.When I got the new hardware out, I also noticed the new longer bolts had 3 Marks and the letters JH on the head.
Correct me if I'm wrong but the rule of thumb for bolts is- Count the Marks and add 2 for the grade ie: 3 marks +2 = grade 5
6 Marks +2= Grade 8 which is how the OEM bolts were marked. I'm going to replace them with bolts I know are grade 8.I would suggest you all check yours and see if you have the same.I figured I better throw this out here ,because it's a saftey issue .Contacted Unisteer but they didn't get back to me
