Bolt designation
While doing a motoir mount R & R I noticed that some of the bolts in the crossbar and suspension differed in appearance from others in similar use - the suspect bolts appeared to be a more silvery color and, maybe my imagination, but they also seemed lighter in weight.
What bolts are specified for these heavy weight bearing applications and how do I identify them ?

Look at the markings on the head of the bolts. If it has 8.8 then it is probably original or the same.
Cad plating can be silver in color.
U.S. markings are 6 lines for grade 8, 3 lines for grade 5.
When the PO replaced the mounts before he may have replaced with new bolts also, new bolts are often cad plated, what is important is the markings.
