reaming tr3 lower wishbone arm bushings

[richard triplett <rtriplett25@yahoo.com>]

I'm taking the lower wishbone arms and new bushings
for trunnion end to machine shop soon. I know the
bushings need to be reamed after being pressed into
arm, but to what spec? I am reusing the trunnions and
I have a suspision that the trunnion extensions might
be off a bit from spec tolerances. Should I just have
the machinist mic each trunnion extension and ream to
that dimension for the corresponding arm? 

This is for a 1961 TR3A BTW.

Thanks!
