Hmmmm.  I'll have to try that one.

The latter is correct.  Press out the old, press in the new, then ream.

GAAAA! (General expression of panic.)  DON'T USE AN ADJUSTABLE REAMER!
The two bushings have to be reamed together and perfectly in line with each 
other.  To use an adjustable reamer, you would have set the size, to ream 
one bushing, then adjust, then ream the other, and somehow have both 
reamings come out perfectly concentric.  Good luck.  There is a proper 
(non-adjustable) tool that reams both bushings in one pass, and gets them 
concentric.  Borrow one of those, or have a local shop that has the proper 
tool do it.

Don't make the mistake I made. trunnions go on the kingpins with he part 
that takes the shock arm TOWARDS the brake disc.  The car looks pretty 
darned funny the other way.  (i.e. \   / is the front view)
