Anyone Know the Torque Settings on U-bolts?

I'm redoing some of the suspension and wanted to find out what the torque setting would be for the u-bolts?

It's on a '56 Chevy wagon and it's lowered 1.5 inches in the rear and it's a semi torquey car. I don't know if those points matter but I threw 'em in there just in case. Thanks!

 

I believe it is 90lb. and do them again in 50 miles, and then once more at 100. But I would like to have someone back me up on this!

 

Here is a chart that should help. I mentioned 90lb becuase thats what I was told when I had new bolts made at the local spring shop. Looks like it depends on the bolt diameter.

Thanks man! 90 sounds about right to me, I just wanted to confirm it.

 

Dang, just going to search this tonight! Perfect timing, thanks.
