Core support bushing replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone know the size of the bolts used for the core support bushings when replacing the body mounts? Mine were completely rusted together and had to cut them out. I need to go get some at the hardware store and hoping maybe someone can tell me the size of the bolts.

Thanks.

My 86 has a bolt 1/2" x 12 x 5 1/4" grade 8 but am unsure if earlier models are same.
