I've got a steering box out of a 88 GTA and would like to put it in my 91 RS. Can anyone tell me if it would be a quicker ratio? What were the available steering box ratios by turns stop to stop?

 

Here's some general info (I'd like to give credit, but I don't recall where I found the info):

• “WS” – 1982-1992 Camaro – 12.7:1 ratio (just like your Z/28, this may be the box that you Z originally had.

• “XH” – 1985-1992 Camaro – 12.7:1 ratio (this box was also installed on Z/28’s and other high performance Camaros; it has slightly more steering effort required than the WS box.) NOTE – I believe this box was used on cars originally equipped with 16” wheels

• “WN” – 1982-1985 Camaro – 14.1 ratio

• “WP” – 1982-1985 Camaro – 13:1-15:1 variable ratio (used in Berlinettas, least steering effort required of all third gen. Camaro steering boxes)

• “JL” – 1986-1992 Camaro – 14.1 ratio (base Camaro steering box)

ok this is interesting and all, but what about the firebird-T/A-S/E-WS6/7 boxes, in which no one ever posts or asks about

always wanted to confirm that mine is 12.7, or not

or if the firebirds even used the same ratios/boxes as the camaros at all?


and where do you find this two letter code on the boxes exactly ?

is it stamped in or raised or ink or ?

thanks
