In the pile of parts I received for my 1975 1500 were these new bolts that match the old driveshaft bolts. However I don't know if they are the right strength or not. Any idea as to the markings ARB T stand for?

Thanks

ARB is a brand name. Those look to be ungraded bolts - soft. The real ones should be at least grade 5, three marks around the head. Grade 8 is recommended by some, 5 marks around the head.

Near as I can find, ARB is supplied aftermarket by Moss. But lacking grade marking can be grade 2 at best. Pay attention to the nut as well.
