Need help on U bolts

[vht]

I'm building a truck style susp for a car I'm doing, can anyone tell me what size U bolts that say a 70 V8 truck had on the rear end? Since they used 1 on each side, I know they were pretty healthy, but for the life of me I can't remember the diameter. Also, where to purchase also. I found poly bushing kit on Ebay. I asked this in the 67 to 72 section and all I got was a guy telling me to crawl under my trk and measure, since I haven't got a trk I'll ask on here. Thanks.

They are 3/4".
