[TR] Steering rack

[Jim Henningsen]

Thanks.  I I heard from one of our experts, Dave at TRF, and he stated at the
early 4s have a rack without a steel flange.  The later 4a-6 have the flange
for mounting.  So it looks like someone put a 4a rack in the car sometime in
the past.  The good news is that I have a early straight 4 rack on my parts
car.  Time to put the gloves on and get out the wd40 anD wrenches.
Cheers,
Jim Henningsen

assemblies (not available) for the same numbers as the mounts. There is
apparently a replacement rack for the later one only. George Hahn's photo is
the later rack and mount.

early rack is bolted to vertical mounts on the frame. The aluminum flange in
your photo appears to be round, not flat on the bottom so I might wonder if it
is neither the early or late rack. You also mentioned that the tie rod ends
are screwed all the way on to the tie rods--that's not right. Should be maybe
an inch of threads showing on each side.
