[Shotimes] Loose Steering Rack

[Peter Chase]

Since I bought my 92 MTX back in December, I've been annoyed by a
large amount of play in the steering wheel which makes it hard to
track straight on the highway and exacerbates torque steer around
town.  It feels like the problem is at the coupIing between the rack
and the column because I can feel when the all the slack is taken up
and the rack starts to provide resistance.  I read the article about
tightening the pinch bolt where the rack attaches to the column and
tried to tighten the bolt but it was already cinched down.  Even after
backing off the bolt and retightening it, the play was still there. 
Is there a way to somehow take up the slack in the coupling or am I
loking at replacing the rack.  If the latter is my only option, do I
need to replace it with a SHO-specific rack or will a reman SLO rack
(Ford part # F3DZ3504AX) do?
Thanks,
   Pete
