Paul,

 I measured the 2-pack injectors on the primary fuel rail when I got home
 tonight, Best I can tell, it is 1.0" center to center.

 Well I guess it is a die cast housing which might be needed
 to feed the injectors. That makes it hard to make one with
 an ordinary mill. Here are some old dwgs and pictures of the
 fat injector holder. I made this one (one inch center to center)
   on my my cheap Chinese mill. Took lots of time.

Neither the injector holders Bruce Turentine made for my A/C
application, or the fuel rail that came with the throttle bodies that I
got from Tweakit for the car are very sophisticated.  Both ends of the
injector seem to need a hole that will be snug on the 'O'-ring on that
end and some way of clamping them together.  'O'-ring seals do need
a smooth finish.
