Possibly but how critical are they?
For replacement or accuracy in make?
You are right, the Suspension units are bolted to the axle frames and the trailer frame sits on top, the ubolts hold it together..
But as you can see from the picture below of the stern swinging arm, they are pretty rusted and although they hold it to the frame, my concern as a non engineer is how safe is it when it's swinging/bouncing around at 60mph. ??
I've been thinking that I may be being a little......anal!
However these are the swinging arm roller assembly bolts....
Here's the cut ubolt
And here's the difference, not very clear really in the photo but you should be able to see the difference between the old and new. They are different sizes but the bend should be the same.
