Paul the rear beam Barry bracket fingers will need to move when the
bolt is tightened to apply crush pressure on the bushing.  Make the
two fingers independent and slot the bolt holes is what I am
thinking.  This will make the bracket self aligning on the "X"
axis.    Also, according to the catalogue the bushing hole i.d. is .
79" not  .75 inch.     Jerry

Not really move as there is a steel spacer inside the Barry
rubber bushings. Yes I forgot to fix that hole size on the drawing
I sent. Barry improved the design.

In order  to compress the rubber bushing until it stops against the
steel spacer, the fingers will have to move as the bolt is
tightened.  Jerry

Do you have a 2001? If so How much does it have to move?

In theory:

C + C + .375 = .485 + .485 + .375 = 1.345

D = 1.25 so it must be compressed .095"  I see what you
are saying.

Make two 4130 angles from .125" thick 4130 and slot the 1/4 inch
bolt hole where the long .2500 inch bolts attaches them to the beam.
Or just drill them out to .2975" diameter.
