Is there any reason the Pat's has to be tighten with these bolts onto the lift arm? Should they be kept loose so that the Pat's has some "sideways swivel movement" when the arms are raised and lowered?
Yes, I had a similar concern when I installed the Pat's,,,
I tossed the original bolts, and replaced them with all Grade 8 bolts,,
I also selected lengths that eliminated the use of the jam nuts,,,

I think I remember using at least three different lengths of Grade 8 bolts,,
I thought about using Grade 9, but, that would have been over-kill,, the Grade 8 have been perfect.
The install looks better when the nuts are eliminated.
Some of the bolts are tightened completely,, so they are jammed,,,
Having the Pat's adapters rigid has worked well for me, CAT I or CAT II attachments,,,
