How much (if any) does this effect the steering radius of a 69 nova??

Cant say for certain if it will be the same on your 69 but my 72 certainly seems a lot tighter when making close manouvers I also changed to coilovers and tubular A arms
good luck:yes:

we put a rack in a 67..it was a chris alston chassis set up and you can do a uturn in your driving lane!! big improvement!!

The rack I ran on my car made every turn a pain. It seamed everything was a 3 point turn. Thats one of the reasons why I went back to an upgraded Delphi box.

Good luck
