Maybe his 73 240Z steering rack is broken and he has a spare from a 260<img src="http://www.zclub.net/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>??

240Z and 260Z steering racks are different. The changeover date is August 1973. 240Z racks will have a clamp-on snubber on the main tube. 240Z rack has circular input for pinion with press-in oil seal, 260Z rack has two bolt retainer at pinion input. 240Z rack has narrower mounting points and therefore the mounting bushes are different (thin side wall 240Z, thick side wall 260Z). A 260Z 2+2 rack is different to a 260Z 2 seater - UK lock to lock 2.6 turns 2 seater, 3.1 turns 2+2 (except for rest of Europe where they are the same) and 15.8:1 ratio 2 seater vs. 18:1 ratio 2+2! A 240Z is 2.7 turns lock to to lock and 17.8:1 ratio.
However, both use the same track rod ends, gaiters and inner track rod ends and the engine cross-member is the same (supercedes with upwards compatibility), so the rack will physically fit with the appropriate bushes. 260Z racks may have less mileage on them, but all Z racks are coming to the end of their useful life now! From the figures above you might regard a 2 seater 260Z rack as an upgrade in spec. compared to the 240Z original.

That's very interesting that a 260 2 str has a quicker rack than a 240, which was my reason for questioning "why".
Zed2k - If your 240 rack has had it and you have a 260 rack spare then it seems reasonable that you carry out the conversion. If you are just after a more direct steering feel then consider fitting shorter steering knuckles. I've fitted then to my car and it has reduced the lock to 2.25 turns.

Thanks for all the answers I was going to change it because whoever took the rack off the car (along time ago) used a massive hammer and killed the ends Doh. so as mike suggests I will do the upgrade and as you said I will uprate the steering knuckle and mounting bushes. This will hopefully give me peachy steering.
Thanks
