I need a need steering column for my 91 Firebird. What years and what models can replace it? Thanks.

Any Third Gen Camaro or Firebird from 90-92 ( anything with an Air Bag will be fine). The 89 coulmns Had VATS but no Air Bag. 88 & earlier columns will have less features ( air bag, Vats ) and the wiring for the wiper system is slightly different.

P.S. Try to locate a column with the Key AND Vats module that matches the key. Otherwise you will need to re-program the VATS module to read the Chip Key correctly.
