Offset shackles

Well maybe if you'd post picture I could! But I'd bet money you've got an MP kit.

Bob, the bottom line is it doesn't matter who made your offset hangers. Unless you have a car that was built well outside of the factory specifications for your spring mounting and frame rail locations there isn't 3/4" of space to move the front hanger inboard before it hits the rails. I don't have to know everything about every part ever made, all I have to know is the chassis specs. And there isn't 3/4" of space there.
You must not read well, I don't know who made mine , and u evidently didn`t read or understand what I said I had to do to get them installed. The person I bought them from couldn`t even get them in his car. ????
That being said, I`m thinking about mini tubbing it anyway.
