rear spring bolts
 

What size bolts are required for the cups that hold the coil spring to the frame and trailing arm? I would like to buy the bolts before I take the truck apart.
Thanks

1/2 inch bolts with washers/lockwashers. I think the uppers are 1 1/2 inches long. Lowers are 4 1/2 or 5 inches long thru the trailing arms. I was advised to get grade 8 bolts and hardware.
