Thanks Tom, but I knew all that..
What I was wondering was what tie rod ends
or machining on the steering arms did you
have to do?   The Alpine arms are slightly
longer than the MGB arms and should help
even more,  that was part of Doane's race
mods IIRC.  I haven' t heard of anyone else
using the stock rack like you.  Did you have
to "unbend" the rack arms and did you make
sure you didn't run out of rack ball joint
travel?  You should be able to do your own
precision alignment using the "strings"
method, I do.
