[DeTomaso] A-arm bushings...should they require machining?

Dear Joe,
I don't know.
I do know that twenty odd years ago when I converted
both Panteras to polyurethane bushings from Pantera Performance Center, they
went in with just finger/hand pressure. No press needed. Obviously, they
must have been smaller than yours and I don't understand why there is such a
great difference.
Puzzled, Chuck Engles

I have removed the bushings from the front A-Arms and have found their ODs
to be a consistent 1.184". the A-arm bore IDs varied slightly around
1.181". this makes sense as the IDs would be 30mm with the bushings
oversized for MY expected press fit of ~ 0.003".
NOW, the new bushing ODs vary around 1.189". to ME, that is way too much
press and could plastic yield the A-arm bores.
Is it expected to machine the new bushing ODs? (Pretty common practice for
new parts to be oversized for field fitting in the machines I use to work
to allow for possible damage/wear.)
OR
Throw away the micrometers and get a bigger press?
