Hey everybody,

Thanks to this awesome site, and the great information and how to's I've found, in a few days I'll be replacing the radius arm bushings on my 92' Eddie bauer. Which is not only a huge step into the world of dyi for me but a very exiting one as well. It seems that a previous owner had already replaced the bushings because there are already bolts where the factory rivets would be located and no heat shield on the passenger side ( Which I think is why it looks like pancake ). What I'm concerned about are if the current bolts are Grade 8. Is there a way of finding out, or should they be replaced to be on the safe side, regardless? TM:salute:

Awesome, Thanks, They do have the six Radial lines. They also have the letters JH stamped in the center of the markings, not sure if that is of any significance. Appreciate it.
