Not certian why you want this information but am guessing a non-stock application. Yes?
You may or may not realize that just about every place that makes springs also makes "u-bolts". You can get them to your specification and quite reasonable at that...

The green bible has all the specs also, defined as Dave/Green Bay showed in his post.
