My steering used to be very lose and it got to the point where it was steering more to the left than right. Actually so much that it rubbed the frame and upper control arms when turning left. I went to napa and just ordered a new box for a 73 cuda. Its alots stiffer than most muscle cars ive driven and only costs about $140. However if you want to pay over double for a new sports car feel I guess try the firm feel. If you had a really good suspension I could definatly see buying the firmfeel box. What im getting at is your cars is not going to handle like a viper form a steering box.
