1970 C10 and C20 Leaf Spring U-bolt Difference? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was under the impression that there was a difference in the u bolt thickness between the C10 and C20s or are they the same. I thought the C10 u bolts were 1/2" and the C20 were like 5/8". Is this true or are they the same. Thanks

the 3/4 ton ones are 5/8 inch and you can get them at your local napa store, i've bought a few sets over the years.
the 1/2 ton 2wds are smaller diameter, not sure if they're 1/2 or 7/16.
in case either of you need the plates, i have one set of each for 2wd trucks
