Thanks! I am looking at so many websites, I am forgetting to notice if the chart is for Chevy or GMC. However, the information I found said they put the drum brake system on the drive shaft on 1 1/2 tons and 2 tons. That is part of my confusion as well. Do you know where on the frame they stamp the serial number as well?

Thanks for the help!
Mike
