Don,
I drilled my trailing arms without the aid of a drill press. Just be
very careful in lining up the drill perpendicular to the trailing arm
surface. One or two studs weren't perfect but the backing plate and hub
went on easily.
You can just as easily do the drilling with the arms on or off the car
IMHO. I did mine off the car because, well, everything was off the car.
I'm doing a frame off resto so the arms were in my basement.
I used 5/16" corse thread Heli-coils, red Locktited into place. I
bought studs that had coarse thread on one end and fine thread on the
other. Having the coarse thread into the aluminum trailing arm is
supposedly stronger than fine thread.

Subject: Using E-Z LOC inserts on Trailing arm studs.
If I would like to add E-Z LOC inserts or Heli-Coils to my TR250
trailing arm studs, is there a reason to do it now, during the frame
off, while the trailing arms are out of the car or can I do it just as
easily later while the trailing arms are still in the car?
I guess the real question is do I need to get the trailing arms out of
the car and use a drill press, or can I drill out the stud holes free
hand with a hand held electric drill?
From Nelson's right up I would assume I would use E-Z LOC inserts with
a 5/16-24 Internal fine thread to match the existing studs, and a
7/16-14 coarse external thread. Or should I replace the studs and use
studs with 5/16-18 coarse threads?

Or should I use Heli-Coils? If so, why and what sizes.
