Fark $3100 for that stay away, I replaced my sterring rack in my R31 when it died (was slipping in housing) and also had a new cam installed and total was $1500 i think.
Repco or the like should have tie rod ends, just jap have longer ones to im pretty shore. and just give the rack a good clean and wait till it goes.
and yea a wheel alimenght is a good idea and wheel balance.
also look at other work shops, they may do it alot cheeper.
