Used shift knob off a 1987 Shelby CSX. Note it has the word "pull" on the cap. 
It will fit 87 Shelby CSX, 88 CSX-T, 89 CSX VNT, 87 Shelby Lancer, 87 Lancer Shelby, 87 Daytona Shelby Z, 88 Shelby Z, 89 Daytona Shelby, and pretty much all 5 spd G,H,P, and J body vehicles model year 1987-1989.  
 
 This would NOT be correct for someone with a car such as a Shelby Charger or Omni GLH for two reasons:
 
1) Because to get to reverse on those cars you had to PUSH down and then move the shifter to the left to engage reverse.
and
2) The thread size on the bottom of this knob (where it threads on to your shifter) is incorrect for L-body vehicles.    Note that we do carry the L-body specific shift knobs elsewhere on our site.
